base angles
Two angles that have the base as a side.
Base angles are the angles formed by the two congruent sides of an isosceles triangle and the base that connects them. In an isosceles triangle, two sides are identical in length, causing them to form equal angles with the base.
The measure of each base angle in an isosceles triangle can be found by using the following formula:
Base Angle = (180 – Vertex Angle) / 2
where the vertex angle is the angle formed at the top of the triangle, opposite to the base.
For example, if the vertex angle of an isosceles triangle is 100 degrees, we can find the measure of each base angle as follows:
Base Angle = (180 – 100) / 2 = 40 degrees
Therefore, each base angle in this triangle would measure 40 degrees.
It is important to note that this formula only works for isosceles triangles, where two sides are congruent. In a scalene triangle, where all three sides are different lengths, the base angles will not be congruent.
