2. The sum of the exterior angles of a convex polygon is ° Remember that a straight angle is ° The interior angle is always supplementary to an exterior angle at that vertex. They always add to °, even for a concave polygon. Convex case: In the case of convex polygons, where all the vertices point "outwards" away form the interior, the A convex hexagon has exterior angles that measure 80, 68, 84°, 56°, and 40°. Which of the following is the mea… Get the answers you need, now! Sal demonstrates how the the sum of the exterior angles of a convex polygon is 360 degrees. I believe it was a pentagon or a hexagon. and what we had to do is figure out the sum of the in particular exterior angles of the hexagon so that this angle equaled A, this angle B, C, D and E. The way that we did it the last time we said, well A is Note: For the polygons that follow (quadrilateral, pentagon, hexagon), these applets will work best if the polygon is kept CONVEX. If you don't remember what this term means, click here for a refresher. 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 Convex Polygon Exterior Angles. The exterior angle of a polygon is defined as the angle formed bt extending the sides of a polygon. The exterior angle sum theorem states that the sum of the exterior angles of a convex polygon is 360°. If a convex polygon is regular with “n” number of sides, then each exterior angle of a convex polygon is A convex hexagon has exterior angles with measures 34°, 49°, 58°, 67°, and 75°. What is the measure of an exterior angle at the sixth vertex? 7. An interior angle and an adjacent exterior angle of a polygon form a linear pair. How can you use this fact as another method to fi nd the measure of each exterior A convex hexagon has exterior angles with measures 34, 49, 58, 67, and 75. The measure of an exterior angle at the sixth vertex is 77. Solution: 34+49+58+67+75 +x= 77. Find the measure of the exterior angles of a polygon. Click Create Assignment to assign this modality to your LMS. Exterior Angles in Convex Polygons. Measure of angles on the outside of a polygon formed by extending a side. % Progress . MEMORY METER. A hexagon is a six-sided figure, the sum of its interior angles is . You should notice that every time we add a side, the sum of the angles go up by . So, if you want to know the sum of the interior angles of a certain polygon, just make a quick chart starting with a triangle at and keep on adding as you increase the sides.
