A point shows the EXACT LOCATION of an object.A point is a basic unit in geometry.A point is represented by a DOT.A point is represented by, example : .P or .AA point has no dimension that is no length and no breadth.
Line segment
ALSO TAKE RUNING NOTES AND I WILL EXPLAIN THEM.
Hlo class, tdy we will be learning about Basic geometrical ideas.So, lets start with point
A plane is a smooth, flat, two-dimensional surface that extends infinitely in all directionsA plane does not have boundariesA plane has two-dimensions that is LENGTH AND BREADTH
RAY
now about plane!
A Line has one dimension that is length. Represented by AB.
A LINE is a collection of points that extends infinitely/endlessly in both directions along a straight path.
A
ANGLE
B
now lets learn line
A LINE SEGMENT is a part of a line that has defined endpoints and has a fixed length. Represented by AB
Add 2 end points on the line to make a line segment
The SYMBOL for RAY is
A RAY is a part of a line with an endpoint that extends infinitely/endlessly in one direction.
→
Example is a sun's ray of light in space
An angle is represented by the SYMBOL ∠
An ANGLE is formed when two rays (arms) meet at a common point called a VERTEX.
there are various types of angles, based on measurement. The names of basic angles are Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle, and full rotation
And that's all...so hope u guys understood it and tmrw we will learn the definition of types of angles.
