Drag the green points or press the "Random" button to adjust the angle. Click on the protractor to measure each angle, then classify the angle as acute, right, obtuse, or straight. Step 2. Common Core Connection for 4th Grade Recognize that angles are formed when two rays share a common endpoint. 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. Most of us know how to use the compass, but when using a protractor there are a few subtle things to highlight that become important in our studies of geometry. We measure angles using a protractor, and we use units called degrees, which are the units that measure the value of angles. Make practicing measuring angles with a protractor fun!

A straight angle. Students will practice measuring angles with a protractor with this fun digital activity. Measuring an Angle Protractor is a geometrical instrument that looks like the letter D. The angles are marked from 0° to 180° on the edge in clockwise direction as well as in anti-clockwise direction. Click on the protractor to measure each angle, then classify the angle as acute, right, obtuse, or straight. Actually, it’s just a pinch. Protractor. Understand concepts of angle measurement. When measuring an angle, the center point should align with the center point of the protractor, and one arm or ray should align with the base of the protractor. The straight edge is where the pivot point begins and where you will compute and determine angles. O is the midpoint at the baseline of the protractor. Rotate the angle 10-degrees to return to 20-degrees. Place the origin or center point (usually a small hole) of the protractor exactly where the sides of the … 4.MD.6 Measuring angles with a protractor Reading protractors to measure angles ID: 272606 Language: English School subject: Math Grade/level: Grade 4 Age: 8-12 Main content: Measuring angles Other contents: Add to my workbooks (12) Download file pdf Embed in my website or blog Here are some step-by-step instructions, provided by ScienceStruck, on how to use a protractor.
