Question

Helpppp quickkkkk plzz

Answer 1

The Pythagoras Theorem is a^2  +b^2 = c^2 if this is true then you have a right triangle.   So I think they are looking for side lengths in the first box.  

Answer 2

The Pythagorean theorem proves a triangle is a right triangle if the square of the height plus the square of the base equals the square of the hypotenuse ( A^2 + b^2 = c^2)
So the answers should be:


1. Side lengths

2. a^2 + b^2 = c^2

3. is a right triangle
