Identify and calculate co-interior angles with this one-page maths worksheet.

## Looking for a Co-Interior Angles Worksheet?

Once your students can name and classify acute, obtuse, right, straight, reflex and revolution angles, there’s little point in repeated lessons involving these same angle types. Why not allow them to dip their toes in the advanced angle pool of alternate, co-interior, corresponding and vertically opposite angles?

Co-interior angles are often identified using a 匚 shape. On parallel lines, co-interior angles are supplementary. This means that the angles add up to 180°.

This worksheet provides students with the opportunity to identify the co-interior angles on various sets of parallel lines. Students are also required to calculate the size of the missing angle.

An answer key is included with your download to make marking fast and easy!

## Tips for Differentiation + Scaffolding

In addition to independent student work time, use this worksheet as an activity for:

• Whole-class review (via smartboard)
• Guided maths groups
• Independent practice
• Homework assignment
• Summative assessment

Some students may need a reminder of what co-interior angles are when completing the worksheet. Our Advanced Angles Factsheet is the perfect resource to paste into your students’ workbooks as a visual guide to refer back to while completing the worksheet.
