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?

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

anonymous · Answer

1)Pythagorean Theorem says  a^2+b^2=c^2
2)Yes by using sine and cosine functions
3)Same as number 2. sine and cosine functions work both ways
4)I dont know this one sorry
