line segment AB

2017-12-06 03:32:09 UTC

A line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints
Examples of line segments include the sides of a triangle or square

Distance AB

rp_kirana — 2017-12-06 03:33:47 UTC

definition : distance AB is the length of the line segment AB
notation :

concurrent lines

2017-12-06 03:34:20 UTC

In geometry, three or more lines in a plane or higher-dimensional space are said to be concurrent if they intersect at a single point.

7)Reflex Angle

-Definition
:The reflex angle is the larger angle. It is more than 180° but less than 360°
