ANSWERS:

I. Based on this video's title, I think it will explain the Pythagorean Theorem with some visual examples. As the title include the word 'Tips', maybe it will also include some tricks to elaborate your Pythagorean equations easier and faster. Five words I think I am going to listen in this video: hypotenuse, squared root, sum, triangle, and Pythagoras.

II. 1. It is a theorem named after the Greek mathematician, Pythagoras, used to find the length of one of the three sides of a rectangle triangle, having the other two, without measuring it. This theorem only works in rectangle triangles.

2. Pythagorean Theorem only works with rectangle triangles. That means, you need to have a 90° in it.

3. Hyp othenuse is the opposite side of the rectangle angle of a rectangle triangle. It can also be found as the longest side of this geometric shape.

4. A rectangle triangle is formed by two 'sides' or 'legs', and one 'hypothenuse'. That makes up the three sides of the triangle.

5. First, he wrote the basic equation of Pythagorean Theorem. Then, he introduced for each letter, a and b, their true values of each side called legs. When he had the equation ready to resolve, he followed the math steps to find the hypothenuse, in out case is side c, and finally found its length.
