Special Right Triangles:
Isosceles Right Triangle:
The isosceles right triangle is also called the 45-45-90 triangle
because of the measures of the angles.
Theorem: The 45-45-90 Triangle:
The hypotenuse of a 45-45-90 triangle is 2^½ times as long as a
leg.
Theorem: The 30-60-90 Triangle:
The hypotenuse of a 30-60-90 triangle is twice as long as the
short leg and the longer leg is 3^½ times longer than the
shorter leg.
