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.

A transversal intersects two parallel lines. If one of the alternate interior angles is 65°, what is the measure of the other alternate interior angle?

If a transversal cuts two lines and the alternate interior angles are not equal, what can you say about the two lines?

If angle A and angle B are supplementary and angle A is 110°, what is the measure of angle B?

If angle x and angle y are vertically opposite angles and angle x = 120°, what is angle y?

If the sum of two angles is 180° and one angle is twice the other, what are the measures of the two angles?

If two angles are complementary and one angle is 37°, what is the other angle?

If two angles are supplementary and one angle is 0°, what is the other angle?

If two lines are cut by a transversal and the corresponding angles are equal, what can you conclude about the two lines?

If two lines are not parallel and do not intersect, what are they called?

If two lines are parallel and a transversal cuts them, and one of the corresponding angles is 75°, what is the measure of the other corresponding angle?

If two lines are parallel and a transversal cuts them, which angles are equal to each other?

If two lines are perpendicular, what is the angle between them?

If two lines are perpendicular, what is the relationship between their slopes (if the lines are on a coordinate plane)?

If two lines intersect, how many pairs of vertically opposite angles are formed?

What is the measure of an angle that is supplementary to a right angle?

What is the measure of each angle if two lines intersect and form four equal angles?

What is the name of an angle that is greater than 90 degrees but less than 180 degrees?
