When two straight lines intersect (cross each other), four angles are created around a point which total 360 degrees.

​

Vertically Opposite Angles

​The pairs of angles that are opposite each other measure the same number of degrees and a equal.

​

Vertically Opposite Angles

​These pairs of angles are called vertically opposite angles

Parallel lines run alongside each other in pairs.

​

They would never meet.

​

There are always the same distance.

​

Parallel and Perpendicular Lines

​Perpendicular lines are pairs of lines that meet at a right angle.

​

They are marked by using square at the point where they meet​
