Angles in parallel lines corbett maths

An introduction to alternate, corresponding and co-interior angles in parallel lines. Parallel lines are lines which are always the same distance apart and never meet. Arrowheads show lines are parallel.

Supercharge your learning. Corresponding and alternate angles are formed when a straight line passes through two parallel lines. Parallel means that two lines are always the same distance away from each other, and therefore will never meet. Parallel lines are marked with matching arrows as shown in the examples below. Drawing a straight line that passes through two parallel lines creates a whole bunch of angles that are all related to each other. How these angles are related is explained by 4 simple rules. Vertically aligned angles are the same.

Here we will learn about angles in parallel lines including how to recognise angles in parallel lines, use angle facts to find missing angles in parallel lines, and apply angles in parallel lines facts to solve algebraic problems. Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal. We can use the information given in the diagram to find any angle around the intersecting transversal. Alternate angles , co-Interior angles, and corresponding angles. Vertically Opposite angles Vertically opposite angles are the same size. We know that vertically opposite angles are equal and we can show this around a point within our parallel lines:. If we extend the transversal line so that it crosses more parallel lines, the angles that are made are maintained throughout the diagram for any line that is parallel to the original line AB. Top Tip : for the same intersecting transversal, all the acute angles are the same size , and all the obtuse angles are the same size.
