Question

How sould i prove that angles of a quadrilateral is 360

Answer 1

Answer:

If we draw one diagonal to quadrilateral we will get 2(two) triangle

example: triangle ABC and triangle ACD.

we know that.

sum of the angles of a triangle is 180 degree.

sum of the angles of quadrilateral

ABCD = sum of angle of triangle ABC + sum of angle of

triangle ACD.

= 180 degree + 180 degree

= 360 degree.

hope this helps u.
