Description:
This mindmap gives the idea about point, lines, line segment, ray and angles and their certain types
-
Basic Geometrical Concepts
-
Point (.)
A location represented
by a dot. -
Line
Collection of infinitely
many points- Parallel lines
Lines that do not meet each other
on a plane at any point. - Perpendicular lines
Two lines form a right angle to
each other and meet
at a single point.
- Parallel lines
-
Line segment
A part of a line that has two
endpoints. -
Ray
A line with a single endpoint
that extends infinitely
in one direction. -
Angle
Endpoints of two rays meeting
at a common point.- Acute angle
Between 0° and 90° - Right angle
measures exactly 90° - Obtuse angle
Between 90°and 180°
- Acute angle
