Pythagorean Theorem: In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.
Converse: If the square on the hypotenuse is equal to the sum of the squares on the other two sides of a triangle, then it is a right triangle.

No. The Pythagorean Theroem can ONLY be used on right triangles. Also, If you know one side of the square you know all sides of the square because a square has four equal sides.
Right triangle (apex)
That it is a right triangle with the longest side c facing the right angle.
* To find the hypotenuse, take the square root of (a2 + b2). * To find either of the two shorter sides, take the square root of (c2 - b2)
~(A => B) is ~B => ~A That is to say, the converse of "A implies B" is "the converse of B implies the converse of A". In this case: If a shape is not a parallelogram then it is not a rectangle.
