Teach your students to identify and calculate supplementary angles with this one-page maths worksheet.
Looking for a Supplementary Angles Worksheet?
Supplementary angles add up to 180°. This means that if you were to divide a straight angle into several smaller angles, the total sum of the supplementary angles would be 180°.
This worksheet provides students with the opportunity to calculate the size of the missing supplementary angle on a variety of straight angles.
An answer key is included with your download to make marking fast and easy!
