This 12-question quiz covers the basic types of angles and how they relate to one another. You will work through fill-in-the-blank and true or false items, with prompts such as What angle measures exactly 90 degrees? and Which are complementary angles? A simple way to keep two tricky terms straight is that complementary angles add up to 90 degrees while supplementary angles add up to 180, so the pair with the bigger total is the one for a straight line. You will also confirm why the two sides of a right angle are called perpendicular. Recommended level: beginner to intermediate.

This 12-question quiz works through the parts of a circle and the formulas that connect them. You will identify relationships and run calculations with items like What is the formula for finding the circumference of a circle? and The radius of a circle is 6 cm. What is the diameter? The handle on all of it is the value of pi, roughly 3.14, which links a circle's distance around to the distance straight across. Once you remember that the diameter is simply twice the radius, the rest of the formulas tend to fall into place. Recommended level: intermediate.

This 11-question quiz is about finding the perimeter, the total distance around a shape. It mixes formula recall with calculation, asking things like Which is the formula for finding the perimeter of a triangle? and Find the perimeter of a square having side length of 4 cm. The shortcut worth holding onto is that for any regular shape, where all the sides are equal, you can just multiply one side length by the number of sides. It also stretches to less common shapes like the octagon, so it is good practice beyond the usual square and rectangle. Recommended level: beginner to intermediate.

This 12-question quiz is all about naming polygons by their number of sides. You will answer fill-in-the-blank and true or false items, with prompts like What polygon has 7 sides? and ___ is a polygon with 10 sides. A pattern that makes these much easier to remember is that most of the names come straight from Greek number prefixes, so penta means five, hexa means six, and the list keeps building from there. You will also sort out what makes a polygon regular versus complex. Recommended level: beginner to intermediate.
