To which shape(s) does the Pythagorean theorem apply?

• All triangles

• Right triangles only

• Some right triangles and some isosceles triangles 

• Right triangles and circles.

Which side of a right triangle is the hypotenuse?

• The side opposite the right angle

• The shortest side

• The side adjacent to the right angle
