Lines and Angles

Math ⇒ Geometry

Lines and Angles starts at 6 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Lines and Angles. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Define a transversal in geometry.

Explain the difference between complementary and supplementary angles.

Explain why vertically opposite angles are always equal when two lines intersect.

Given that angle A and angle B are supplementary and angle A is 125°, what is the measure of angle B?

If the measure of one angle is 3 times its complement, find the measure of the angle.

If the sum of two adjacent angles is 180°, what is the relationship between them?

If two lines are cut by a transversal and alternate exterior angles are equal, what can you say about the two lines?

If two lines are cut by a transversal and one pair of corresponding angles are not equal, what can you say about the two lines?

If two lines are cut by a transversal and the sum of the interior angles on the same side of the transversal is 180°, what can you conclude about the two lines?

If two lines are parallel and a transversal cuts them, and one of the corresponding angles is 65°, what is the measure of the other corresponding angle?
