base angles of an isosceles triangle
The base angles of an isosceles triangle are the two angles that are opposite to the equal sides of the triangle
The base angles of an isosceles triangle are the two angles that are opposite to the equal sides of the triangle. In an isosceles triangle, two sides are congruent, meaning they have the same length, and these sides are referred to as the legs of the triangle. The third side, which is not congruent to the legs, is called the base.
The base angles are formed by the base and one leg of the isosceles triangle. Since the two legs have the same length, the base angles are also congruent, meaning they have the same measure.
Let’s say the two equal sides (legs) of the isosceles triangle have length ‘a’, and the base has length ‘b’. The base angles will be denoted as angle A and angle B.
By the Isosceles Triangle Theorem, we know that the base angles are congruent. So, we can represent their measures as ‘x’. Therefore, angle A and angle B are both equal to ‘x’.
In summary, in an isosceles triangle with base ‘b’ and legs ‘a’, the base angles (angle A and angle B) are congruent and have the same measure, represented by ‘x’.
