Question

If the angle of the triangle are equal to three angles of another triangle what about the sides opposite to equal angles​

Answer 1

Step-by-step explanation:

Angles opposite to equal sides of a triangle are equal. Sides opposite to equal angles of a triangle are equal. Each angle of an equilateral triangle is of 60°. If three sides of one triangle are equal to three sides of the other triangle, then the two triangles are congruent (SSS Congruence Rule).

Answer 2

Answer:

If the angle of the triangle is equal to three angles of another triangle then the sides opposite to equal angles are congruent.

Step-by-step explanation:

As we know that the isosceles triangle theorem states that if two sides of a triangle are congruent, then angles opposite those sides are congruent and if angles opposite those sides are congruent, then two sides of a triangle are equal.

Therefore, by the isosceles theorem, if there are two triangles that have one side common and one side and one angle are equal to each other then their opposite angle will also be equal.
