Which sides of a right triangle are called the legs?

• The two shortest sides

• The side opposite the right angle and one adjacent side

• The two sides forming the right angle

• The two longest sides

What is the Pythagorean theorem formula?

• a^2 + b^2 = c^2

• a^2 - b^2 = c^2

• a^2 + c^2 = b^2

• b^2 + c^2 = a^2
