Advanced Geometry Section 2.5 Addition and Subtraction Properties Learner Objective: Students will apply the addition and subtraction properties of segments and angles.
Learner Objective: Students will apply the addition and subtraction properties of sebments and angles. Opener: If the complement of an angle is 40 less than the supplement of the angle, find the measure of the angle. Let x = the angle then 90 - x = complement of the angle and 180 - x = supplement of the angle Solution so 90 - x = 180 - x - 40 +x +x 90 = 140 ! Not Possible

Learner Objective: Students will apply the addition and subtraction properties of sebments and angles. Using the Addition and Subtraction Properties in Proofs. 1. An addition property is used when the segments or angles in the conclusion are greater then those in the given information. 2. A subtraction property is used when the segments or angles in the conclusion are smaller than those in the given information.
