Tilted Squares

Stage: 3 Challenge Level: Challenge Level:1

It's easy to work out the areas of most squares that we meet, but what if they were tilted?

problem icon

On the Edge

Stage: 3 Challenge Level: Challenge Level:2 Challenge Level:2

Here are four tiles. They can be arranged in a 2 by 2 square so that this large square has a green edge. If the tiles are moved around, we can make a 2 by 2 square with a blue edge... Now try to. . . .

Climbing

Stage: 5 Challenge Level: Challenge Level:1

Sketch the graphs of y = sin x and y = tan x and some straight lines. Prove some inequalities.

problem icon

Area L

Stage: 5 Challenge Level: Challenge Level:2 Challenge Level:2
