Identify acute, right, obtuse, straight, reflex and revolution angles with this cut-and-paste sorting worksheet.

## Identify and Name Angles

One of the most fundamental skills when it comes to working with angles is being able to recognize and name the various types of angles.

Each angle type has its own distinct size or size range. The measurements of these angles are as follows:

• Acute – 1 degree to 89 degrees
• Right – exactly 90 degrees
• Obtuse – 91 degrees to 179 degrees
• Straight – exactly 180 degrees
• Reflex – 181 degrees to 359 degrees
• Revolution – exactly 360 degrees

This simple sorting worksheet has been designed to familiarise your students with these six angle types. Students must cut out the angles provided and paste them into the correct column of the table.

## 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 each of the angle types are while completing the activity. Our Types of Angles Anchor Charts are the perfect resource to display in your classroom as a visual guide to refer back to while completing the worksheet.

Because this resource includes an answer sheet, we recommend you print one copy of the entire file, then make photocopies of the blank worksheet for students to complete.
