The two congruent legs of an isosceles triangle are also called congruent sides. An isosceles triangle is a two-dimensional geometric figure containing two sides that are of equal length.
Know MoreThe two congruent sides of an isosceles triangle form the two base angles that are also congruent, which means that both angles have the same measure in degrees. The third interior angle of an isosceles triangle, which is the opposite angle of the base, is called the vertex angle.
The height, or altitude, of an isosceles triangle is represented by a line that divides the isosceles triangle into two equal parts, forming two right-angled triangles in the process. The two congruent sides of the isosceles triangle then form the longest sides of the two right-angled triangles.
Learn more about GeometryThe common formula to find the area of an isosceles triangle is area equals 1/2 * base * height of triangle. The height is the line bisecting the two equal sides of the triangle and intersects the midpoint of the base.
Full Answer >Congruent refers to two things being the same exact shape and measure. For example, if two angles are congruent, the degrees of each angle are identical.
Full Answer >An isosceles triangle is a specific type of triangle where only two of the side lengths and two of the internal angles are equal. There are also other types of triangles like equilateral triangles and scalene triangles.
Full Answer >To show that two triangles are congruent by the SSS (side-side-side) theorem, all three corresponding sides must be shown to be of equal length. The letters SSS stand for the three sides of the two triangles.
