## Words To Know

• Leg - In right triangles (triangles that have one 90 degree angle) the legs are the two sides that join to form the right angle.  They are the sides adjacent to the right angle.
• Hypotenuse - In right triangles the hypotenuse is the side that connects the two legs and creates the two angles that are not right angles.  It is the side across from the right angle.
• Pythagorean Triple - A pythagorean triple consists of three rational integers such that a, b, and c correspond to the equation for the pythagorean theorem a2 + b2 = c2.
• Converse - The reverse of an "if" and "then" statement.  So the converse of the pythagorean theorem would determine if a triangle is a right triangle.
