Question

Find the sum of angles 1,2,3,4,5 in a star

Answer 1

Answer:

180°

Step-by-step explanation:

Find the sum of angles 1,2,3,4,5 in a star

Here we have used a , b , c , d , e  in place of 1 ,2 , 3 ,4 , 5

the sum of angles a , b , c , d , e in a star = 180°

Here In picture you can see a triangle

where one angle = a

Other two angles = b + c   & d + e

(exterior angle of triangle = Sum of other two interior angles of triangle)

Hence a + b + c + d + e = 180° ( sum of angles of a triangle)

Hence sum of angles a , b , c , d , e in a star = 180°
