WebAnswer: A regular decagon has 10 lines of symmetry. Let's look into the lines of symmetry of a decagon. Explanation: The lines of symmetry can be drawn through the vertex and midpoints of each edge. A regular polygon of n sides has n lines of symmetry. A decagon has 10 sides. So, it has 10 lines of symmetry in total. WebAn edge is a line segment between faces. A face is a single flat surface. Let us look more closely at each of those: Vertices. A vertex ... And this pentagon has 5 vertices: Edges. …

WebA closed two-dimensional diagram made of straight lines is called a polygon. A pentagon is a type of closed polygon. It is a polygon with 5 sides and 5 angles as well as 5 vertices. … WebGet yourself some card stock, draw yourself a real nice regular pentagon or whatever polygon you are working with, label the vertices on both sides as 1 through n (1 to 5 in your case).

WebDiagonals of Polygons A polygon 's diagonals are line segments from one corner to another (but not the edges). The number of diagonals of an n-sided polygon is: n (n − 3) / 2 Examples: a square (or any quadrilateral) … WebJan 16, 2024 · Polygons are straight-sided, flat shapes that close in a space. This means every polygon: Is two-dimensional. Uses only line segments to create its sides. Has an interior and exterior. The word "polygon" comes from the Greek and means "many angles," because all simple polygons have as many sides as they have angles. WebDec 9, 2024 · The simplest answer is that a pentagon has $5$ sides, $5$ angles. By extending the sides, you could get as many as $40$ angles ($4$ per intersection of $2$ lines, $\binom {5} {2} = 10$ intersections). Pentagons with $2$ parallel sides will have $36$ angles (those $2$ lines will not intersect). – Joshua Wang. Dec 9, 2024 at 17:17. the prince hair salon
