Question

1. If I know the lengths of two sides of a right triangle, how do I find the third?
2. Could I find the two missing side lengths of a right triangle if I only know one side length and one angle measure (other than the 90 degree angle)?
3. Could I find the two missing angle measures if I know some of the side lengths of a right triangle?
4. What makes a triangle a “special” right triangle? How can special right triangles help me find side lengths?

Answer 1

1. Pythagorean theorem. a^2 + b^2 = c^2

Answer 2

c being the hypotenuse or long side

Answer 3
