What is the base angle theorem?
Understand the Problem
The question is asking for an explanation of the base angle theorem, which relates to the angles in an isosceles triangle. It seeks to clarify what the theorem states and its implications for triangle geometry.
Answer
In isosceles triangles, angles opposite congruent sides are congruent.
The Base Angle Theorem states that in an isosceles triangle, the angles opposite the congruent sides are congruent.
Answer for screen readers
The Base Angle Theorem states that in an isosceles triangle, the angles opposite the congruent sides are congruent.
More Information
The Base Angle Theorem applies specifically to isosceles triangles, which have two equal sides and, consequently, two equal angles opposite those sides.
Tips
A common mistake is not accurately identifying whether a triangle is isosceles, which can lead to incorrectly applying the theorem.
