Question

a group of children prepared some decorative pieces in the shape of a star for the orphans in an orphanage show that angle a plus angle b plus angle c plus angle d plus angle e plus angle f is equal to 360 degree

Answer 1

Step-by-step explanation:

In △AEC,

∠A + ∠E + ∠C = 180° ...(i) (Angle sum property of a triangle)

Similarly, in △BDF,

∠B + ∠D + ∠F = 180° ...(ii)

Adding (i) and (ii), we get

∠A + ∠B + ∠C + ∠D + ∠E + ∠F = 360°
