Answer:
Base Angles
Step-by-step explanation:
Given:
The triangle is an Isosceles triangle.
We need to find the angles across from the legs are called what angles?
Step-by-step explanation:
An isosceles triangle is a triangle which has two congruent sides.
The congruent sides of the isosceles triangle are called the legs.
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 isosceles triangles is that their base angles are always congruent. This is called the Base Angles Theorem.
Hence in an isosceles triangle with two congruent sides the angles across from the legs are called as Base angles.
