An isosceles right triangle always has two angles that are:

• Congruent

• Congruent and both 45 degrees

• Congruent and both 60 degrees

When given two sides of a right triangle, you can find the third side using:

• The Pythagorean theorem

• The rules for a 45 - 45- 90 triangle

• The rules for 30-60-90 triangle
