A worksheet on classifying angles as acute, right, obtuse, straight or reflex. There is a table of practice identifying angles given their measures. Solutions are included.
Engage and Challenge Your Students with Angle Classification!
Looking for a clean, no-prep way to assess or consolidate your students’ understanding of angles? This comprehensive practice worksheet is designed to help students master the art of classifying angles by their measures.

Going beyond just the basics, this resource challenges students to identify a full range of angles, making it perfect for Key Stage 2 (KS2) geometry units, Key Stage 3 (KS3) revision, or a quick pre-assessment!

What’s Included?

• Comprehensive Practice Grid: A structured student worksheet featuring 16 different angle measurements to classify.

• Full Range of Angle Types: Students will classify angles across all major categories: Acute, Right, Obtuse, Straight, and Reflex ranging from 4 to 325 degrees.

• Teacher Answer Key: A fully completed, check-marked answer sheet for fast, effortless marking or student self-assessment.

  Angle Types Covered:

• Acute (e.g., 4, 17, 35, 89 degrees)

• Right (90 degrees)

• Obtuse (e.g., 91, 100, 140, 167 degrees)

• Straight (180 degrees) Reflex (e.g., 182, 183, 193, 224, 278, 325 degrees)

Why Teachers Love This Resource:

• Zero Prep: Just print and photocopy! Ideal for morning work, homework, maths hubs, or independent practice.
• Includes Reflex Angles: Many worksheets stop at 180 degrees. This sheet safely pushes your students’ geometric thinking by including reflex angles up to 325 degrees.
• Clear Layout: The grid format helps students stay organized as they tick off the correct angle classifications.
