Base angles theorem The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.

Aug 3, 2023 · Using the properties of isosceles triangle, the two theorems along with their proofs are given below. What is the Isosceles Triangle Theorem Also known as the base angle theorem.

Search Base Angle Theorem The Base Angle Theorem states that in an isosceles triangle, the angles opposite the congruent sides are congruent.

Converse of the Base Angles Theorem The converse of the base angles theorem, states that if two angles of a triangle are congruent, then sides opposite those angles are congruent.

The other side is called the base. The angles between the base and the legs are called base angles. The angle made by the two legs is called the vertex angle. One of the important properties of …

When the altitude to the base of an isosceles triangle is drawn, two congruent triangles are formed, proven by Hypotenuse - Leg. The altitude creates the needed right triangles, the congruent legs of …

Here is a theorem associated with isosceles triangles. Base angles theorem states that if two sides of a triangle are congruent, then the angles opposite them (called base angles) are congruent.

Dec 4, 2025 · The Base Angles Theorem, in its simplest form, states that if two sides of a triangle are congruent, then the angles opposite those sides are also congruent. This type of triangle, where two …

We accept that an isosceles triangle, which has (at least) two congruent sides, also has congruent base angles. Label the congruent angles in the figure. Now we prove that the base angles of an isosceles …
