Question

3) Write angle sum property for triangles.​

Answer 1

One common property about triangles is that all three interior angles add up to 180 degrees. This now brings us to an important theorem in geometry known as Triangle Angle Sum Theorem. According to the Triangle Angle Sum Theorem, the sum of the three interior angles in a triangle is always 180°.

Answer 2

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
