Question

find the sum of angle 1,2,3,4,5,6​

Answer 1

Answer:

360°

Explanation:

angle1,3 and 5 are angles in one triangle

therefore by angle sum property

angle1+angle3+angle5=180°. equation1

Similarly angle2,4and6 are angles in one triangle

therefore by angle sum property

angle2 + angle4+angle6=180°. equation2

Adding equation 1 and 2

angle1+2+3+4+5+6=180°+180°=360°

Explanation for angle sum property:

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
