In an isosceles triangle with two congruent sides, the angles across from the legs are called angles.

The angles across from the legs are called base angles

Step-by-step explanation:

we know that

The isosceles triangle is a triangle with two equal angles and two equal sides

The two equal sides are called legs and the third side is called base

The two equal angles are called base angles and the third angle is called vertex angle

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
