the measure for a regular rectangle is 69in. by fudge you and measure it yourself.

135
Tha will depend on how many sides the regular polygon has.
The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
15 degrees
Each exterior angle will measure 9 degrees
Each interior angle will measure 162 degrees
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
Providing that it's a regular decagon then each exterior angle will measure 36 degrees
A regular quadrilateral is a square. As to the measure, the answer depends on the measure of WHAT? An angle, a side, the diagonal, area, perimeter, etc.
