Notes A right isosceles triangle can also be referred to as a 45- 45-90 triangle
The length of the hypotenuse of a 45-45-90 triangle is 10. What is the length of legs?
Notes Any right triangles with congruent angles need not necessarily have congruent side lengths however, they will always have equivalent side length ratios. These are called trigonometric ratios. These can be recalled using the mnemonic SOHCAHTOA
What are the sine, cosine, and tangent of angle T?
