A right triangle, also known as a right-angled triangle, always has one angle at 90 degrees. The side directly opposite this angle is known as the hypotenuse, which is the longest side of a triangle.
Know MoreIf the lengths of two sides of a triangle are known, it is possible to calculate the length of the third side using Pythagoras' theorem. This theorem states that the sum of the square of the hypotenuse is equal to the sum of the squares on the other two sides. This theorem only applies to right triangles.
When a right triangle has sides with lengths that are each an integer, it's called a Pythagorean triangle.
Learn more about ShapesThe hypotenuse of a right triangle is calculated by finding the square root of the sum of the squares of the triangle's legs. It can be expressed using the formula c = √(a^{2} + b^{2}), where a and b represent the legs of the triangle and c indicates the hypotenuse.
Full Answer >The length of the altitude of a right triangle is equal to the geometric mean of the line segments of the hypotenuse. The geometric mean can be thought of as the average length of the two line segments.
Full Answer >A right triangle either has one or no lines of symmetry. An isosceles right triangle, one with two sides of equal length, has one line of symmetry. A scalene right triangle, one with no sides of equal length, has no lines of symmetry.
Full Answer >Use the Pythagorean theorem to calculate the hypotenuse of a right triangle. A right triangle is a type of isosceles triangle. The hypotenuse is the side of the triangle opposite the right angle.
