45-45-90 Triangle Theorem In a 45-45-90 triangle, the hypotenuse is times as long as each leg.

Situations Given a Leg Given the Hypotenuse

Given a Leg

Given the Hypotenuse

30-60-90 Triangle Theorem In a 30-60-90 triangle, the hypotenuse is twice as long as the shorter leg, and the longer leg is times as long as the shorter leg.

Situations

Given the “1” side

Other 2 Situation Whenever we don’t have the “1” side. We will find it first. Simply divide by what you have to get the “1” side, then multiply the “1” side by what you need.

Given the 2 Side
