👉 Learn how to determine the sum of interior angles of a polygon. A polygon is a plane shape bounded by a finite chain of straight lines. A regular polygon is a polygon whose sides are congruent ...

Grab a pen and draw a figure. Follow a few rules: keep your lines straight, don’t pick up your pen, don’t cross the lines, and finish at the spot where you started. You’ll have a polygon. Polygons are ...

STEP 1: Using a pencil and ruler, draw a horizontal line. Set the compass to the width of the line. Place the compass at either end of the line and draw two arcs that cross in the middle. Image ...

The sum of the angles inside any polygon can be found by spitting the polygon into triangles. Sum of interior angles = 180(n – 2) where n is the number of sides In a regular polygon all the angles are ...
