Final answer:
To draw an obtuse angle, start by drawing a line segment and then measure an angle greater than 90 degrees. The supplement of an obtuse angle is obtained by subtracting the measure of the obtuse angle from 180 degrees.
Step-by-step explanation:
To draw an obtuse angle, start by drawing a line segment. Then, using a protractor, measure an angle greater than 90 degrees and draw it such that it opens away from the line segment. This angle is an obtuse angle.
The supplement of an angle is the angle that, when added to the original angle, forms a straight line (180 degrees). To find the supplement of an obtuse angle, subtract the measure of the obtuse angle from 180 degrees.
For example, if the measure of the obtuse angle is 120 degrees, the supplement angle would be 180 degrees - 120 degrees = 60 degrees.
