Question

state and prove the angle dum property of a triangle​

Answer 1

Answer:

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

Answer 2

Step-by-step explanation:

angle sum property of a angle = A+B+C=180°

suppose a triangle had 3 angles

50°+70°+60°=180° hence this is a triangle

for ex.

50°+90°+10°=150°

hence this is not a triangle as sum of its angles is not 180°
