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. When a pair of parallel lines is cut with another line known as an intersecting transversal , it creates pairs of angles with special properties. Corresponding angles are equal. The lines make an F shape. Notice that the F shape can be upside down or back to front. Alternate angles are equal. The lines make a Z shape which can also be back to front. In this guide. Types of angle Angles at a point and on a straight line Angles in parallel lines Triangles Quadrilaterals Polygons Symmetry.

Parallel means that two lines are always the same distance away from each other, and therefore will never meet. Don't have an account? You must be logged in to vote for this question.

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. We group these angles into three separate types called alternate angles , co-interior angles and corresponding angles.
