1) Special right triangles have properties that allow for determining side lengths without using the Pythagorean theorem. A 45-45-90 triangle has both legs that are congruent and the hypotenuse is √2 times the leg length. A 30-60-90 triangle has the hypotenuse that is 2 times the shorter leg and the longer leg is √3 times the shorter leg. 2) Examples are provided to demonstrate using the special right triangle properties to determine unknown side lengths. 3) Relationships between the legs and hypotenuse of 45-45-90 and 30-60-90 triangles are outlined to determine a leg from the hypotenuse or a longer leg from a shorter leg
