# If angles A B C and D E F were measured with a protractor, what does intuition tell you about the degree measures of these angles? To determine

To explain:

About the measure of the angles ABC and DEF, which are measured with a protractor.

Explanation

Calculation:

Given,

First let us measure the angle ABC

Place the notch of the protractor at the point B.

Place the protractor along the sides BC of the angle so that the scale reads zero at the point C on the inner scale.

Use the same scale (inner) and read the angle size by reading the degree measures that corresponds to the second side BA of the angle.

Now, the angle ABC measures to be 80°

Similarly, the angle DEF measures to be 110°

Thus,

ABC=80°

DEF
