Question

If a polygon can be divided into five non-overlapping triangles, find the angle sum of the polygon.

Answer 1

Step-by-step explanation:

heptagon can we divided in to five triangles ,

to find the sum of the angles if the polygone

(the sum of the angles of an n-side polygon is (n-2)×180)

^

this is the theory of the sum of angles of polygons

to find angle sum

number of sides =7

number of triangles=7-2=5

sum of the angle=5×180°=900°

angle sum of 1 triangle is 180°

so,

the angle sum of 5 ∆ is 5×180°=900°
