Classifying and Identifying Angles Worksheets

Based on the measurement, the angles can be broadly classified as acute, right, obtuse and reflex.

This page contains worksheets in identifying types, classifying angles, measure and classify, drawing examples according to the given type, identifying types from multiple rays, classifying angles in geometric shapes, types of angles formed by clocks, counting types and classification charts.

Classifying Angles

Each worksheet has 12 problems classifying types of angles. Level 1 has acute, right, obtuse and straight angles. Level 2 has all angles in level 1 in addition to reflex angle.

Identifying Angle Types

Level 2: Sheet 1 | Sheet 2 | Sheet 3

Measure and Classify

Measure each angle using protractor and identify the type.
