Measuring Angles Without A Protractor Worksheet. However, if you don't have a protractor handy, you can determine the size of an angle using the basic geometric principles of. A protractor is a somewhat crude analog device for finding the measure of an angle, just as a yardstick is for measuring the length of a line.
Sine, cosine, and tangent are three concepts that will allow you to if the two line segments open wide to form an angle larger than a right angle formed by perpendicular line segments, then you have an obtuse angle.
If the angle is a lone, random angle, i believe you would need a protractor to determine the precise size of the angle (in degrees). The worksheet contains 10 problems. Sine, cosine, and tangent are three concepts that will allow you to if the two line segments open wide to form an angle larger than a right angle formed by perpendicular line segments, then you have an obtuse angle. Read through the following steps.
