Question

how to prove angle sum property of triangle​

Answer 1

Answer:

Step-by-step explanation:

LHS

Formula for angle sum property is (n-2)*180

N= number of sides that polygon have

so

n=3

(3-2)*180= 180

the sum of angles of triangle is 180

LHS =180

RHS=180

Thus it prove that sum of angle of is 180 degree
