Answer 1

$\huge\underline{\bf \red{ ᴀɴsᴡᴇʀ }}$

• Angle sum property states that sum of all the interior angles are equal to 180°. For example :- X+ X+ X = 180°

Answer 2

Answer:

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

Proof:

Consider a ∆ABC, as shown in the figure below. To prove the above property of triangles, draw a line PQ←→ parallel to the side BC of the given triangle.
