Circle Quizzes & Trivia

Round and round and round we go, where we stop, nobody knows! Actually, we do... Next stop, geometry quizzes! One of the most basic shapes we know since childhood is the "circle". In geometry though, the circle has a lot of properties and equations associated with it. Are you in shape to answer our quizzes on circles? First, why don't you try out some terminologies involving circles.

Arc, center, diameter, radius; are you any good at this "sector"? How about some problems on area and circumference? Do you think you can make it around these questions? We have questions on different properties and theorems too. Stop going in circles and check out our quizzes. Worrying too much, are you? Relax and get on with the quizzes. We promise, it's going to be as easy as "pi"!
