Interior Exterior Angles Of Polygons By Nicola Waddilove Tpt Task cards increase in difficulty. this activity helps to reinforce the concepts of the interior angle sum theorem, interior angles of polygons, and exterior angles of polygons. this is a great way to visualize that interior angles and their exterior angle will be supplementary! an answer key and recording sheet is provided!. Notice how the interior angle and exterior angle always add to 180°, even for a concave polygon. refer to the figure above. it shows in detail one vertex of the polygon. you can see that the interior angle and exterior angle are supplementary, adding to 180°. as you drag the vertex downwards the polygon becomes concave, with the vertex pushed. Sum of exterior angles = n x 180° – sum of all interior angles… (1) putting the formula for sum of all interior angles in (1) we get, sum of exterior angles = n x 180° – (n 2) x 180° = n x 180° – (n x 180° 2 x 180°) = 180°n – 180°n 360° = 360° hence, sum of the exterior angles of any polygon is 360°. one exterior angle. Step 1. determine whether you’re looking for interior or exterior angles. if we think of the shape as a house, the in terior angles live in side of the house, while the ex terior angles live in ex ile outside of the house. type of angles: step 2. count the number of sides (n) the shape has. step 3.

Although you know that sum of the exterior angles is 360, you can only use formula to find a single exterior angle if the polygon is regular! consider, for instance, the pentagon pictured below. even though we know that all the exterior angles add up to 360 °, we can see, by just looking, that each $$ \angle a \text{ and } and \angle b $$ are. Interior and exterior angles of polygons. calculate the measure of one interior and one exterior angle of a regular octagon. interior: n sides sum = (n 2)180 (8 2)180 = 1080 1080 8=135 exterior: 180 interior = exterior 180 135 = 45 360 8 = 45.
