<span>A regular polygon is a polygon which has sides of equal length and angles between them also equal. The number of sides and angle measurements depend on the shape of the regular polygon. If the shape of the regular polygon is a square, its interior angle is equal to 90° and the exterior angle of 90°. If the shape is a regular hexagon which has 6 sides. The exterior angles add up to 360 divided by 6 angles= 60 °while the interior angle is (180-6)=120°. </span>
Please note that the interior angle and its corresponding exterior angle always add up to 180° (for a regular octagon, the exterior angle is 360/8=45 while the interior angle is 180 - 45 = 135°.
Two lines that are parallel have the same slope. Thus, find the slope of the line (J) thru (4,2) and (5,1), and that will be the answer to your question.
