 Manipulative 2: Length of the hypotenuse of a right triangle Created with GeoGebra 

The length of an hypotenuse of a right triangle can be calculated from the length
of the legs of a right triangle using the
Pythagorean theorem:
a^{2} + b^{2} = c^{2} where a and b
are the lengths of the legs of the triangle and c is the length of the hypotenuse. For example,
if the length of the legs are 3 and 4, the length of the hypotenuse is:
