The most common ratio of the three sides of a right triangle is 3:4:5 (3 is the measure of the short leg, 4 is the measure of the long leg, and 5 is the measure of the hypotenuse). Where a and b represent the two legs of the right triangle and c is the hypotenuse. A right triangle is any triangle that has one right internal angle.Īccording to this theorem, if the length of the legs (smallest sides) are squared and their sum is found, the sum is equal to the square of the hypotenuse (longest side). The Pythagorean theorem simply states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. The Pythagorean Theorem is a mathematical relationship between the sides of a right triangle. The ratio can be found out by using Pythagoras theorem. If you have an isosceles triangle, a triangle where two of the sides are congruent, then their base angles, these base angles, are also going to be congruent. The special feature of these two triangles are that length of the sides of the triangle are in a certain fixed ratio. The ratio of the three sides is a : √3a : 2a, where a is the length of the shortest side. The hypotenuse is two times the length of the shorter leg. The 30-60-90 triangle is formed by cutting equilateral triangle in half. When you bisect any angle in an equilateral triangle, you get two such right triangles. This also means that the length of a leg is equal to the length of the hypotenuse divided by √2. Its hypotenuse is equal to √2 times the length of a leg. If you bisect a square with a diagonal line, you get two triangles that both have two 45-degree angles. This triangle is also called isosceles right triangle as two sides are equal. The 45-45-90 triangle is formed by cutting the square in half along with the diagonal. Two special right triangles are 45-45-90 and 30-60-90. The sum of other two angles will be 90 degrees. In a right triangle, one of the angle is of 90 degrees.
