Big Idea The dimensions of a right triangle can be determined with limited information.
Essential Question: How can Pythagoras help me?

 Mathematical Reflections Pg. 52 (INV 4)   First it is an easy and efficient way to find out the side lengths of a right triangle. Second it has an easy equation form: L1 (squared) + L2 (squared) = H (squared).   In a 30-60-90 triangle leg 2 is always half of leg one. And the angles are obviously 30, 60 and 90 degrees.   In this investigation we worked with the Pythagorean Theorem to figure out side lengths of right triangles or the hypotenuse. It only works for right triangles.
