Below are sample questions representative of the exercises included on this worksheet and related GEO.42 Use segment addition and angle addition skill assessments:

Problem 1Difficulty: Mastery
Point R is between Q and S, and point T is between R and S. QR = 2x + 8 units, RT = x - 3 units, TS = 15 units, and QS = 80 units. Which equation represents segment addition, and what is x?
A(2x + 8) + 80 + 15 = x - 3; x = 20
B80 + (x - 3) = (2x + 8) + 15; x = 20
C(2x + 8) - (x - 3) + 15 = 80; x = 57
D(2x + 8) + (x - 3) + 15 = 80; x = 20
Solution & Explanation:The points are in order Q, R, T, S, so QS is the sum of QR, RT, and TS. The equation is (2x + 8) + (x - 3) + 15 = 80. Then 3x + 20 = 80 and x = 20.
Problem 2Difficulty: Mastery
Ray YZ lies inside angle WYX. m(angle WYZ) = 6x - 2 degrees, m(angle ZYX) = x + 12 degrees, and m(angle WYX) = 4x + 64 degrees. Which equation represents angle addition, and what is x?
A(6x - 2) + (4x + 64) = x + 12; x = 18
B(4x + 64) + (x + 12) = 6x - 2; x = 18
C(6x - 2) + (x + 12) = 4x + 64; x = 18
D(6x - 2) - (x + 12) = 4x + 64; x = 78
Solution & Explanation:Angle WYX is the whole angle. Add the parts: (6x - 2) + (x + 12) = 4x + 64. This simplifies to 7x + 10 = 4x + 64, so x = 18.
Problem 3Difficulty: Mastery
Points A, B, C, and D are collinear in that order. AC = 5x + 1 units, CD = 16 units, and AD = 7x + 9 units. Which equation represents segment addition using AC and CD, and what is x?
A(5x + 1) + (7x + 9) = 16; x = 4
B(5x + 1) + 16 = 7x + 9; x = 4
C16 + (7x + 9) = 5x + 1; x = 4
D(5x + 1) - 16 = 7x + 9; x = -12
Solution & Explanation:Since C is between A and D, AC + CD = AD. Substitute to get (5x + 1) + 16 = 7x + 9. Then 5x + 17 = 7x + 9, so x = 4.
