Edge (geometry)

In geometry, an edge is a particular type of line segment joining two vertices in a polygon, polyhedron, or higher-dimensional polytope. In a polygon, an edge is a line segment on the boundary, and is often called a polygon side. In a polyhedron or more generally a polytope, an edge is a line segment where two faces (or polyhedron sides) meet. A segment joining two vertices while passing through the interior or exterior is not an edge but instead is called a diagonal. (Wikipedia).

What is a central angle of a circle

Learn the essential definitions of the parts of a circle. A secant line to a circle is a line that crosses exactly two points on the circle while a tangent line to a circle is a line that touches exactly one point on the circle. A chord is a line that has its two endpoints on the circle.

Angle Side Relationships in a Triangle - Geometry

This video focuses on the angle side relationships in a triangle. In particular, I show students how to use the idea that the smallest angle is opposite the smallest side. This concept is used to order the sides of the triangle from least to greatest. Your feedback and requests are encour

Nets of polyhedra | Perimeter, area, and volume | Geometry | Khan Academy

We know...."nets of polyhedra" sounds like the title of a bad sci-fi movie about man-eating, muti-headed fish. A polyhedron ("polyhedra" is plural) is nothing more than a 3 dimensional shape with flat surfaces and straight edges (think: cube) Practice this lesson yourself on KhanAcademy.o
