How is Pythagoras theorem used in everyday situations?
The Pythagorean theorem states that the square on the hypotenuse of a right triangle has an area equal of the sum of squares of the other two sides. The Pythagorean theorem was a mathematical fact that the Babylonians knew and used. A triangle with sides a, b, and c (longest) is a right triangle if and only if a² + b² = c². Hence we know how the sides are related if is a right triangle. Common Pythagorean triple are: 3, 4, 5 5, 12, 13 7, 24, 25 9, 40, 41 and 6, 8, 10 All but the last triple are primitive, the last is called a multiple. A regular polygon has all sides equilateral and all angles equiangular. In a triangle, these cannot occur independently. The resulting triangle with sides in the ratio 1:1:1 and angles 60º-60º-60º is discussed. The three most important right triangles are: 3-4-5, the isosceles right (45º-45º-90º), and 30º-60º-90º triangle. 3-4-5 triangle has angle measure of about 37º-53º-90º. Watch especially for these special angles and triangles. The isosceles (2 or m
