On this triangle congruence lesson, you will learn the difference between the Angle-Angle-Side AAS theorem and the Angle-Side-Angle ASA theorem (also known as the asa postulate) when proving triangle congruence and what are same side interior angles?

This lesson answers the questions: How do I prove that two triangles are congruent? What is ASA? What is AAS? What is the difference between ASA and AAS?

Our lessons are perfect for flipped classroom math teachers and students. This lesson is aligned with the common core learning standards for math and the SAT math curriculum as well.

How Many Faces, Edges And Vertices Does A Octagonal Prism Have?
Here we’ll look at how to work out the faces, edges of vertices of an octagonal prism.
We’ll start by counting the faces, these are the flat surfaces that make the 3D shape. An octagonal prism has 10 faces altogether - 2 octagonal faces, as well as 8 rectangular faces.
Next we’ll work out how many edges the shape has, which are where two faces meet. An octagonal prism has 24 edges.
Next we’ll count the corners of the shape(the corners). Get counting! An octagonal prism has 160 vertices.

For the full playlist for the faces, edges and Vertices of a whole lot of 3D shapes go to https://www.youtube.com/playli....st?list=PLjbxBzUM6SL

How to square any numbers in your head - fast mental math trick here: https://www.youtube.com/watch?v=GEuyDHMG0jY

There is barely any calculation needed to mentally find the square a number that ends in five. How fast? The square of 45 is 1225; The square of 85 is 7225; the square of 115 is 12125; the square of 1095 is 1188125....as fast as I can type them I answer them!
The trick is this to faster squaring....
Say we have 65 squared. Get the number that is not 5 ( that is 6) and multiply it by the next number after it (7). Then just write 25 on the end.
So 6 x 7 = 42, our answer is 4225. Really. Simple 'eh?

Charlotte the Scientist Is Squished
by Camille Andros
Illustrated by Brianne Farley
Read by Let's Read Stories

Charlotte is a serious scientist. She solves important problems by following the scientific method. She has all the right equipment: protective glasses, a lab coat, a clipboard, and a magnifying glass. What she doesn’t have is space. She has so many brothers and sisters (she is a rabbit, after all) that she is too squished to work on her experiments! Can she use science to solve her problem? This funny, satisfying story is a playful introduction to the scientific method and perfect for sparking an interest in STEM subjects.

You may have noticed that the internet is terrible at religious discourse. Well, this is not a new phenomenon. In the early 16th century, the Roman Catholic church dominated Christianity in Europe, and the institution was starting to show some cracks. Tensions mounted and protests grew, and eventually, the Protestant Reformation happened. Martin Luther nailed his 95 Theses to the church door in Wittenberg, but the Reformation doesn't exactly begin with Luther, and it certainly doesn't end with him. Today, we're looking at how and why the Catholic church in Europe split, first into two sects, and eventually into a LOT of sects.

In which John Green discusses the strange and mutually beneficial relationship between a republic, the city-state of Venice, and an Empire, the Ottomans--and how studying history can help you to be a better boyfriend/girlfriend. Together, the Ottoman Empire and Venice grew wealthy by facilitating trade: The Venetians had ships and nautical expertise; the Ottomans had access to many of the most valuable goods in the world, especially pepper and grain. Working together across cultural and religious divides, they both become very rich, and the Ottomans became one of the most powerful political entities in the world. We also discuss how economic realities can overcome religious and political differences (in this case between Muslims and Christians), the doges of Venice, the sultans of the Ottoman empire, the janissaries, and the so-called slave aristocracy of the Ottoman Empire, and how money and knowledge from the Islamic world helped fuel and fund the European Renaissance. Also, there's a They Might Be Giants joke.

In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.

If you're interested in learning more about the Russian government's 2022 invasion of Ukraine, check out this vlogbrothers video published on 3/15/2022: https://www.youtube.com/watch?v=mMZYKxgc9TE

In which John Green teaches you how Russia evolved from a loose amalgamation of medieval principalities known as the Kievan Rus into the thriving democracy we know today. As you can imagine, there were a few bumps along the road. It turns out that our old friends the Mongols had quite a lot to do with unifying Russia. In yet another example of how surprisingly organized nomadic raiders can be, the Mongols brought the Kievan Rus together under a single leadership and concentrated power in Moscow. This set the stage for the various Ivans (the Great and the Terrible) to throw off the yoke and form a pan-Russian nation ruled by an autocratic leader. More than 500 years later, we still have autocratic leadership in Russia. All this, plus a rundown of some of our favorite atrocities of Ivan the Terrible, and a visit from Putin!

In which John Green teaches you about the early days of the Civil Rights movement. By way of providing context for this, John also talks a bit about wider America in the 1950s. The 1950s are a deeply nostalgic period for many Americans, but there is more than a little idealizing going on here. The 1950s were a time of economic expansion, new technologies, and a growing middle class. America was becoming a suburban nation thanks to cookie-cutter housing developments like the Levittowns. While the white working-class saw their wages and status improve, the proverbial rising tide wasn't lifting all proverbial ships. A lot of people were excluded from the prosperity of the 1950s. Segregation in housing and education made for some serious inequality for African Americans. As a result, the Civil Rights movement was born. John will talk about the early careers of Martin Luther King, Thurgood Marshall, Rosa Parks, and even Earl Warren. He'll teach you about Brown v Board of Education, the lesser-known Mendez vs Westminster, the Montgomery Bus Boycott, and all kinds of other stuff.
