Web3 nov. 2024 · Regular polygon: All of the angles are of equal size, and all the sides are equal in length. Irregular polygon: Does not have equal-sized angles or sides of equal length. Convex vs. Concave Polygons . A second way to classify polygons is by the size of their internal angles. Convex polygons: Have no internal angles greater than 180°. Web29 sep. 2024 · A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440° . An irregular decagon has sides and angles that are not all equal or congruent. A convex decagon bulges outward, with no interior angle greater than 180° .Jun 19, 2024. Web24 mei 2016 · Times 10 equals 70; each diagonal is counted twice, so the final answer is 35. Now, using combinations and such: There are ( 10 2) ("10 choose 2") pairs of vertices, which equals 45. So there are 45 line segments joining pairs of vertices. Exactly 10 of those are sides of the decagon, the others are diagonals. Answer: 35. flower features crossword
