Q:

What are the congruent legs of an isosceles triangle also called?

A:

Quick Answer

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.

Full Answer

The 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.

  • Q:

    How do you solve for the perimeter of an isosceles triangle?

    A:

    The perimeter of a triangle is the sum of all the sides of the triangle, and you determine the perimeter of any triangle by adding the lengths of all three sides. Since an isosceles triangle has two sides of equal length, start by multiplying the length of one of the equal sides by two. Then, add the product to the length of the base side. The resulting sum is the perimeter of the triangle. Using either a pen and paper or a calculator, you can make these simple calculations in just a few minutes.

  • Q:

    What is altitude in geometry?

    A:

    Altitude in geometry (also known as height) refers to a segment that extends from any vertex of a triangle and is perpendicular to the line found on the opposite side. This term is also employed to refer to the length of this segment.

    How do you find the height of a scalene triangle?

    A:

    To find the height of a scalene triangle, the formula for the area of a triangle is necessary. The equation is area = 1/2hb, where h is the height and b is the base. However, before using this formula, other calculations are required.

  • Q:

    What is a "median" in geometry?

    A:

    A median is a line segment that joins any vertex of a triangle to the midpoint of the opposite side of the triangle. A triangle has three sides and three vertices. Hence, it has three medians. A median divides a triangle into two equal halves of equal area.
