Question

proof tha the sum of exterior angle of a parallelogram is 360°?​

Answer 1

The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon. ... pair, so it has to sum to 180 degrees.

Answer 2

Answer:

to proove a the ans then u just take a example

Step-by-step explanation:

so lets take a parallelogram abcd with the angles each measure with 90 degrees.

so if u add up all the angles of a quadrilateral u need to get 360degrees.

which is angle sum property.

so 90*4 is 360degrees.
