What are the properties of a 45-45-90 triangle?

Back

In a 45-45-90 triangle, the legs are congruent, and the length of the hypotenuse is √2 times the length of each leg.

What is the ratio of the sides in a 30-60-90 triangle?

Back

The ratio of the sides in a 30-60-90 triangle is 1:√3:2, where 1 is the length of the shorter leg, √3 is the length of the longer leg, and 2 is the length of the hypotenuse.

What is the relationship between the angles and sides in a right triangle?

Back

In a right triangle, the side opposite the largest angle (90 degrees) is the hypotenuse, and the other two sides are the legs.
