Define all types of lines and angles.
Answers
Ancient mathematicians introduced the concept of lines to represent straight objects which had negligible width and depth. ... When two rays (part of a straight line) intersect each other in the same plane, they form an angle. The point of intersection is called a vertex.
Answer:
Types of Line
In Geometry, there are basically four types of lines. They are:
Horizontal Lines
Vertical Lines
Parallel Lines
Perpendicular Lines
Horizontal Lines
When a line moves from left to right in a straight direction, it is a horizontal line.
Vertical Lines
When a line runs from top to bottom in a straight.
Parallel Lines
When two straight lines don’t meet or intersect at any point, even at infinity, then they are parallel to each others.
Perpendicular Lines
When two lines meet or intersect at an angle of 90 degrees or at a right angle, then they are perpendicular to each other.
