4th Grade Math Worksheets

Labeling the Vertex and Arms of an Angle | Single Angle

Look at the image and identify the two lines that join to form an angle. Additionally, figure out the point where the two lines meet.

Naming Angles using Three Points | Single Angle

Examine the given figure, identify the two endpoints of the rays that are not in common, and name the angle using the endpoints and the vertex.

Classifying Acute, Obtuse, and Right Angles Using Reference

Scrutinize each image, select the correct option, and identify the angle as acute, right, or obtuse angle.

Measuring Angles | 5° Increments

Use the inner scale of the protractor and measure angles with 5-degree increments.

Drawing Angles | With Protractor - 1° increments

Each resource features six protractors with 1-degree increments. Draw the other ray on each protractor to create the specified angle.

Estimating Acute and Obtuse Angles

Study each angle featured here and estimate the approximate measure of the angle.

Finding Unknown Angles | Angle Addition Postulate - One Pair

Figure out the measure of the indicated adjacent angle, either by adding or subtracting the known angle measures.

Parts of an Angle | MCQs

Read the questions based on parts of angle and choose the appropriate options to complete these exercises.

Naming Angles | Missing Representation

Revise the different ways of naming angles with this compilation, where three of the four possible representations are given. Identify the missing one.

Classifying and Counting: Polygons

Observe each illustration of the angle and identify the number of acute angles, right angles, and obtuse angles in each image.

Identifying Types by Measures

Identify and circle the type of angle specified in the question. In the second part, write acute, obtuse, right,straight, reflex, or complete based on the measure of each angle.

Reading a Protractor | 5° Increments

Learn to measure the size of an angle using a protractor. Read the marking on the inner scale and record your answer.

Drawing Reflex Angles

Place the protractor on the dot, align the base of the protractor with the given ray, and draw the other ray to make an angle with the given measure.

Measuring Angles in Analog Clocks

Observe the minute hand and the hour hand on each clock and find the angle between the hands of the analog clock.

Estimate, Measure, and Compare Angles

Estimate the measures of the pairs of angles, compare and find which angle has a smaller/larger measure and then confirm whether your estimation is correct.
