High School Mathematics - 28.14 Pythagorean Theorem - Examples

 Theorem: In a right angled triangle, the square on the hypotenuse is equal to the sum of the squares of the other two sides. If the length of the hypotnuse is c and the lengths of other two sides are b and a then according to the pythogorean theorem: c2 = a2 + b2 Converse: In a triangle if the square of one side is equal to the squares on the sums of the other two sides, then the angle opposite to the first side is a right angle. To prove: AB2 + BC2 = AC2 Example: Prove that the sum of the squares of the sides of a rhombus is equal to the sum of the squares of the diagonals. Directions: Solve the following problems. Also write at least 10 examples of your own.
