There are 6 types of angles:-
1-Acute Angle -size between 0 and 90 degree.
2-Right Angle--exactly 90 deg.
3-Obtuse Angle-between 90 and 180 deg.
4-Straight Angle-exactly 180 degree.
5-Reflex Angle-between 180 and 360 degree
6-Angle of complete turn-exactly 360 degree.

Perpendicular Line segments:-
When a straight line meets another straight line making an angle of 90 degree,they are called perpendicular to each other.
Parallel line segments:-
The lines,that never meet each other are called parallel lines.
Intersecting line segments:-
The lines that cross each other at a point known as the point of intersection are called intersecting lines.
Hope it will help you!
