1-4 Measuring Angles

Question 1

Linear Pair Postulate

Answer 1

If two angles form a linear pair, then they are supplementary.

Question 2

Protractor Postulate

Answer 2

If two rays that point to coordinates on a protractor are corresponding to each of two values for those coordinates, then the curved distance between those two points is the absolute value of the difference of those values.

Question 3

Angle Addition Postulate

Answer 3

If two adjacent angles exist, then the measure of one angle can be added to the measure of the other angle, and the sum is the measure of a third created angle.

Question 4

Vertical angles theorem

Answer 4

If two angles are vertical angles, then they are congruent.
