Show transcript
An angle is the space between two straight lines which join at a vertex or point.
A protractor is a piece of equipment used to measure and draw angles.
When we measure the angle of light hitting a surface, we measure the angle between that light and the normal line.
The normal line is an imaginary line that is at a right angle to the surface.
