Lines And Angles

animation lines and angles

A Line can be extended on both ends. A line segment cannot be extended on either end. A ray can be extended on one end.

Angle: The inclination between two lines when they meet is called angle. If an angle is equal to 90° it is called Right Angle. If an angle is less than 90° it is called Acute Angle. If an angle is more than 90° it is called Obtuse Angle.
