Video 1: "Geometry Tips : What Is the Pythagorean Theorem? "
I. Before you watch the video answer the following questions. Read the title of the video What do you think this video will be about? I think that this video is going to make clear the origin of the theorem of Pit**__á__**goras, what **IT** is, how and when **IT** should be used     **Good** Mention five words you think you might listen to in the video. 1. Triangle 2. Right angle 3. Hypotenuse 4. Opposite side 5. Adjacent side

**Good** II. Now click on the following link and watch the video. While and after watching, please answer the following questions: [] 1. What is the pitagoream theorem? The pitagoream theorem **WAS** discovered __for__ **(change use "by")** the greek math Pitagoras **WHO** establishe__s__ **established** that in a right triangle, the squared of the hypothenuse __it__ **(omit "IT")** is equal to the sum of the squares __to__ **__(change use "TO")__** __de__ **(worng word)** other__s__ **(omit the "S")** two sides, called catetos **catheti**. __This__ **THESE** sides are the base of the right angle (90°) __that makes to the right triangle__. confusing

**Good** 2. Why is it said to be exclusive? He says that, because __just it__ **it just** works for the right triangles in which as __his__ **its** name tell**S** us one of __his__ three angles is right, that is to say, that **IT** measures 90 exact degrees.

3. What is a hypothenuse? The hypotenuse is the **longest** side __of major length__ in a right triangle and it is equal to the sum of the squares of the catetos. catheti

4. What is the name of the other sides of a rectangle triangle? The name of the other sides is __catetos__, one of them __calls__ **is called** adjacent __cateto__ because it is adjacent to the hypotenuse and other one __calls__ **is called** opposite cateto because it is opposite to the hypotenuse.

5. What steps he uses to solve the problem on the video? The steps that he used, to solve the problem are: 1. He gives a value to "a" and other one to "b", where "a" it is equal to 3 and "b" equal to 4. 2. He applies the formula of the pitagoream theorem, a2 + b2 = c2, where he replaces the values that he assign, that is to say, 32 + 42 = c2. 3.Finally, he solves the squares and the sum, that is to say, 9 + 16 = c2 ,where c2 = 25 and c= + o - 5.

**Good** Nota: los dos (2) que aparecen en la respuesta a la pregunta 5. son el cuadrado de la letra o número anterior, no se porque el wiki me los coloco como un número normal y no como un superíndice. Yes... wikis have problems understanding font changes.. I'll ask my previous students to come to a class to explain you how to introduce formulas in the wikis.
