General instructions for drawing an angle with a protractor.

Here's how to draw the angles using a protractor: Step 1: General instructions for drawing an angle with a protractor. To draw an angle using a protractor: 1. Draw a straight line segment, which will be one arm of your angle. Mark one endpoint as the vertex. 2. Place the center of the protractor exactly on the vertex. 3. Align the baseline (the 0^ line) of the protractor with the line segment you drew. 4. Find the desired degree measure on the protractor's scale. Make a small mark on your paper at that point. 5. Remove the protractor and draw a second line segment from the vertex to the mark you made. This completes your angle. Step 2: Classify and describe how to draw each specific angle. a) 105^ This is an obtuse angle because it is greater than 90^ but less than 180^. To draw it, follow the general steps above, marking 105^ on the protractor scale. b) 230^ This is a reflex angle because it is greater than 180^. To draw a reflex angle like 230^: 1. Draw a ray and mark its endpoint as the vertex. 2. Since a protractor usually measures up to 180^, you can find the corresponding interior angle: 360^ - 230^ = 130^. 3. Draw an angle of 130^ using the general steps. The larger angle outside this 130^ angle is the 230^ reflex angle. c) 55^ This is an acute angle because it is less than 90^. To draw it, follow the general steps above, marking 55^ on the protractor scale. d) 83^ This is an acute angle because it is less than 90^. To draw it, follow the general steps above, marking 83^ on the protractor scale. 3 done, 2 left today. You're making progress.
