Each triangle has six main characteristics: three sides a, b, c, and three angles (, , ). How do you find the hypotenuse of a triangle? The leftmost vertical side, labeled 15. The theorem is generally credited to the Greek mathematician Pythagoras though this is a debatable fact as many scholars believe this knowledge predated him. An isosceles right triangle is a special isosceles triangle that has two angles that are 45 degrees and legs a and b of equal length. 9 + 16 = c multiply. The hypotenuse of the right triangle is the side opposite the right angle, and is the longest side. x = x = units Stuck?

If the lengths of all three sides of a right triangle are whole numbers, the triangle is said to be a Pythagorean triangle and its side lengths are collectively known as a Pythagorean triple. In the case of a 30 60 90 right triangle, the length of the hypotenuse is always equal to two times the length of the shortest leg. WebThis trigonometry video tutorial explains how to calculate the missing side length of a triangle.
