|A line is a path between two points. A straight line is the shortest distance between two point. A line has a length.|
|Parallel lines are two, straight lines that always stay the same distance apart. The lines never meet.|
|An angle is the measurement of the turn between two intersecting lines. Angles are measured in degrees.|
|An angle of 90 degrees is a right angle. Where one line intersects another line at a right angle, the lines are perpendicular to each other.|
What is an angle of 90º called?
A Right Angle is 90º. It is shown as a square on diagrams, rather than as a curve.
Answer: A Right Angle
What is the angle formed by a perpendicular line?
A perpendicular line intersects another line at a right angle, or 90º.
