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 9

If one angle of a linear pair is 120 degrees, what is the measure of the other angle?
If the sum of two angles is 180 degrees and one angle is twice the other, what are the measures of the two angles?
If the sum of two angles is 90 degrees, what are these angles called?
