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.

See sample questions for grade 12

Define skew lines and give an example.

Describe the conditions under which two lines in a plane are said to be parallel.

Explain the difference between corresponding angles and alternate interior angles.

Explain why the sum of the angles at a point is always 360°.

Given that angle 1 and angle 2 are supplementary and angle 1 is 2x + 10°, angle 2 is 3x – 20°. Find the value of x.

Given that two lines are cut by a transversal and the sum of the measures of two interior angles on the same side of the transversal is 180°, what does this imply about the two lines?

Given two lines l and m are parallel and a transversal t cuts them at points A and B respectively. If the angle at A is 120°, what is the corresponding angle at B?
