Question

in the figure, show that angle a+Angle b+angle c+angle d+angle e+angle fis equal to 360degree​

Answer 1

Step-by-step explanation:

we know that,

angleA + angleB + angleC = 180°

and,

angleD + angleE + angleF = 180°

By adding this both we get

angleA + angleB + angleC + angleD + angleE + angleF = 180 + 180

angleA + angleB + angleC + angleD + angleE + angleF = 360°

Answer 2

Step-by-step explanation:

In triangle ABC sum of three angles is equal to 180°.

angle A +angle B +angle C =180°---------(1)

In triangle DEF sum of three angles is equal to 180°.

angle E +angle F+angle G =180°---------(2)

Add (1)&(2)

angle A +angle B +angle C+angle D +angle E +angle F=360°.

Hence proved.
