Geometry is the step sister of the regular math we do every day. True, most of us make very little use of geometry in the usual course of our lives, but those lessons stuck with me, and I found that quite a few questions rang some very old bells. So how about it? Do you think you remember enough to beat our quiz?

Some Relearning Needed

You may not remember much from your old lessons. Maybe you want to take this test again a bit later? If not, have a look below and see where you got it wrong. These tests are designed to make it tricky so don't feel bad! We still have hundreds of other quizzes for you to challenge yourself with.

Good Job

You did pretty good for yourself! You're not among the top scorers, we're afraid, but definitely ahead of the curve. Great to see you still remember some of your geometry lessons, doesn't it feel good to find out you still know this stuff?

Terrific Recall!

You have a mind like a steel trap, it seems, and easily recalled the required math in your head. These challenges may look easy to you but a lot of people find them tricky. So congratulations on being a top scorer! Share this result with others and challenge them to do as well as you!
