Question

Write two sum properties of triangle​

Answer 1

Step-by-step explanation:

Theorem 1: Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Theorem 2: If any side of a triangle is extended, then the exterior angle so formed is the sum of the two opposite interior angles of the triangle.

Answer 2

Answer:

Two sum properties of triangle are:

(i) The sum of all internal angles of a triangle is always equal to 180°.

(ii)The sum of the length of any two sides of a triangle is greater than the length of the third side.
