angle of a regular polygon is 144°, find the number of sides. ... Note: You can’t use the Triangle Exterior Angle Theorem with the given information. You should ...
So five corners, which means a pentagon. this means there are 5 exterior angles. since they all have to add to 360 you can divide 360/5 = 72. You can also check by adding one interior angle plus 72 and checking if you get 180. vertex, regular, irregular, concave, convex, interior angle, exterior angle, tessellate, tessellation Explain your reasoning. o Which is greater, the measure of an exterior angle of a regular triangle or the 4. Repeat for a pentagon. (Draw a convex pentagon. Draw two diagonals from the same vertex.)
