Question

Proof that,angle1+angle2+angle3+angle4+angle5+angle6=360degree

Answer 1

Step-by-step explanation:

Let the angles of one triangle be angle 1,angle 2,and angle 3.

Ans angles of other triangle be angle 4,angle 5, and angle 6.

According to the property of measures of angles of triangle.

angle 1+ angle 2+ angle 3=180°.........(1)

also,

angle 4+ angle 5+ angle 6=180°..........(2)

adding eq. (1) and (2)

angle 1+angle 2+ angle 3+ angle 4+ angle 5+ angle 6=180° + 180°

angle 1+ angle 2+ angle 3+ angle 4+ angle 5+ angle 6 = 360°

.........Hence proved.

Answer 2

Step-by-step explanation:

angle 1 + angle 2 + angle 3 =180

angle 4 + angle 5 + angle 5= 180

now add 180+180=360

hence it is proved
