What is the Pythagorean theorem?

• The Pythagorean theorem involves trigonometric functions

• The Pythagorean theorem only applies to equilateral triangles

• The sum of the lengths of the sides is equal to the length of the hypotenuse

• The square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

• Parallel lines are two lines that are perpendicular to each other.

• Parallel lines are two lines that form a right angle.

• Parallel lines are two lines that intersect at one point.

• Parallel lines are two lines in a plane that never intersect.
