Answer 2

Answer:

For triangle DEF, let the angles are x,y and $z$

then x + y + z = 180°

$\sf \purple{∠DFP=180° −x}$

$\sf \purple{∠EDQ=180° −y}$

$\sf \purple{∠FER=180° −z}$

Add these three equations, we get

∠DFP + ∠EDQ + ∠FER = 540° −(x + y + z)

$\dag \rm \red{=540° −180° =360°}$

• Hence, ∠DFP + ∠EDQ + ∠FER = 360°
