Finding the Hypotenuse
The hypotenuse of a right triangle is the side that is opposite of its right angle. Sometimes we have problems that ask us to find the missing hypotenuse of a right triangle. This video describes how to use the Pythagorean theorem to find the hypotenuse, but only when the length measure of the two legs is known. (1:16)

Space Diagonal
The Pythagorean theorem is useful when we need to find the length of a space diagonal in a rectangular prism. This video describes how the space diagonal passes through the space between vertices, instead of the bases or lateral faces. In other words, it is the diagonal that joins two opposing vertices in the prism, or the two vertices that don't share a face with each other. (1:48)

Pythagorean Theorem Converse
This video describes the converse of the Pythagoreum Theorem. If we know that the sum of two square sides in a triangle equals the square of the third side, we can conclude that the triangle is a right triangle. Pythagorean triples are commonly seen side lengths that indicate when a triangle is a right triangle. Knowing these triples will save time when in calculations related to the Pythagorean theorem.

45 45 90 Triangles
A 45 45 90 triangle is a special type of isosceles right triangle where the two legs are congruent to one another and the non-right angles are both equal to 45 degrees. This video describes how to use the Pythagorean theorem to find the missing legs or hypotenuse of 45 45 90 triangles. (4:17)

Distance Formula
This video explains how to derive the distance formula, which is used to find the straight distance between two points in a coordinate plane, by Using what we know about the Pythagorean theorem. The distance formula is a standard formula that allows us to plug a set of coordinates into the formula and easily calculate the distance between the two. (4:26)

(12/12)Battlefield: The Battle for Russia
This fast paced episode of "Battlefield" chronicles the titanic war in the east, that eventually decided World War II in Europe. Despite numerous warnings from the Communist spy networks: the Lucy Spy-Ring the Red Orchestra Richard Sorge, and pleadings from Churchill and FDR, through ultra decrypts, Stalin discounted all invasion warnings. Stalin felt that all these alarming reports was actually an attempt to divide agreements between the Soviet Union and Nazi Germany, by the British and America
