Relationships in Angles
B. Determine whether the statement ∠TAU is C. Determine whether the statement ∠UAX is
complementary to ∠UAY can be assumed from the adjacent to ∠UXA can be assumed from the
f gure. f gure.
A. yes A. yes
B. no B. no
Answer Answer
Skill Practice!
For Exercises 1–6, use the f gure at the right and a protractor.
1. Name two acute vertical angles.
2. Name two obtuse vertical angles.
3. Name a linear pair.
4. Name two acute adjacent angles.
5. Name an angle complementary to ∠EKH.
6. Name an angle supplementary to ∠FKG.
7. Find the measures of an angle and its complement if one angle measures 18 degrees more than the other.
8. The measure of the supplement of an angle is 36 less than the measure of the angle.
Find the measures of the angles.
ALGEBRA For Exercises 9–10, use the f gure at the right.
→ →
9. If m∠RTS = 8x + 18, f nd x so that TR ⊥ TS.
10. If m∠PTQ = 3y – 10 and m∠QTR = y, f nd y so that
PTR is a right angle.
