Triangles: Pythagorean Theorem, The
This clip introduces the Pythagorean Theorem, named for the Greek mathematician Pythagoras. In addition to explaining the theorem itself, the clip explains how it is commonly used, including as a way to determine if a triangle is a right triangle, a...
Common Dimensions of Right Triangles
There some common right triangles in which all three sides are integers, such as a triangle with sides measuring 3, 4, and 5. Any triangle with sides that are multiples of these integers, called a similar triangle, you can be sure is a right triangl...
