What is the base angles theorem?
Understand the Problem
The question is asking for an explanation of the base angles theorem, which is a fundamental concept in geometry related to isosceles triangles. It states that the angles opposite to the equal sides of an isosceles triangle are also equal.
Answer
If two sides of a triangle are congruent, then the angles opposite those sides are congruent.
The base angles theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.
Answer for screen readers
The base angles theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.
More Information
The Base Angles Theorem is applicable specifically to isosceles triangles, where at least two sides are congruent.
Tips
A common mistake is assuming that this theorem applies to all types of triangles instead of just isosceles triangles.
