Although, in general, triangles do not have special names for their sides, in right triangles, the sides are called the hypotenuse, the opposite side and the adjacent side. The names change depending on which angle is th...

A triangle with two equal sides is called an isosceles triangle. The angles opposite the equal sides in an isosceles triangle are also equal. The third, unequal side of an isosceles triangle is called the base of the tri...

When the lengths of all sides of a triangle are added, the result is called the perimeter of the triangle. In general, a perimeter is the distance of the curve that borders a lamina or a two-dimensional closed planar sur...

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.

The 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 = √(a2 + b2), where a and b represent the legs of the ...

The SSS congruence postulate states that if all three sides of one triangle are congruent to the corresponding sides of another triangle, the triangles themselves are congruent. Triangles are congruent if, when one is su...

The centroid of any triangle, right triangles included, is the point where the angle bisectors of all three vertices of a triangle intersect. Given a triangle made from a sufficiently rigid and uniform material, the cent...
