Take this ten-question multiple-choice quiz to practice angle relationships from Common Core standard 7.G.B.5. Each question has exactly one correct answer. The explanation after each question names the angle relationship and points out the most common mistake.
What is the complement of \(57^{\circ}\)?
What is the supplement of \(112^{\circ}\)?
What is the measure of the angle marked ?
What is the value of \(x\)?
Two complementary angles measure \(x^{\circ}\) and \((x+20)^{\circ}\). What is \(x\)?
What is the value of \(x\)?
Two vertical angles measure \((3x+5)^{\circ}\) and \((5x-15)^{\circ}\). What is the measure of each angle?
Which statement is always true?
Two supplementary angles measure \(x^{\circ}\) and \(3x^{\circ}\). What is the smaller angle?
What is the value of \(x\)?
🎉 Quiz complete!
Remember:
- Complementary angles add up to \(90^{\circ}\).
- Supplementary angles add up to \(180^{\circ}\).
- Vertical angles are equal in measure.
- Adjacent angles share a vertex and a side but do not overlap.
- To find an unknown angle, write an equation from the angle relationship and solve it.
