Measuring Angles Using a Protractor Worksheets
Angles are an important concept in geometry, and hence it becomes vital for grade 4 and grade 5 children to learn to measure them. The size of the angle is the turn from one arm of the angle to the other, and to measure this, we require a protractor that comes with an outer and an inner scale. Bolster practice in measuring angles using a protractor starting with 5-degree increments and moving to a single-degree increments, measuring reflex angles, solving for x and much more. Begin your practice with our free sample worksheets and subscribe for the entire collection.
Is the angle between the two rays with a common vertex 40° or 60°? Learn the ropes of using the inner scale of a protractor to measure angles with 5° increments.
Place the midpoint of the protractor on the vertex, line up one arm with the base line of the protractor, measure the angles with 1-degree increments using the inner scale in these pdfs on measuring angles.
Angles that measure more than 180°, but less than 360° are reflex angles. Encourage students to determine the size of each reflex angle using the protractor in this set of measuring reflex angles worksheets.
Angles can be measured using the inner or outer scale of the protractor. Direct students to use the inner scale if the angle opens to the right, and the outer scale if the angle opens to the left, so they can easily measure the angles.
Utilize this batch of printable exercises on measuring angles for children to practice using both the inner and outer scales, while determining the size of the angles with 1-degree increments.
First, measure the angles using your protractor, and then classify them as acute, obtuse, right, straight, or reflex angle.
Exercise the brains of your 4th grade children as they measure each angle, arrange the angles based on the size, and decode the names of the animals in these measuring and ordering angles puzzle worksheets.
Get kids to measure the angle first, and then equate the expression to the size of the angle, followed by isolating x, making it the subject, and solving the expression in these pdfs on measuring angles and finding x.
Offered in these pdf measuring angles revision worksheets is a blend of rays, shapes, and clocks. Check for yourself how well your 4th grade and 5th grade learners can measure angles in this variety of exercises.
