Kala - Co-interior Angles on Parallel Lines

Author:Kuruman GeoGebra Intervention Programme, Taylor Burnett, Tim Brzezinski
Topic:Angles
In this section, we will investigate one final pair of angles formed when two parallel lines are intersected by another line (known as a transversal). The applet below shows examples of co-interior angles:

Use the applet above to investigate co-interior angles. In your own words, describe what co-interior angles are.
