What can you discover by accurately constructing some right angled triangles with integer edge lengths and their inscribed circles (incircles)?
If you make some conjectures, can you prove them?
Share ideas below about what you have discovered.
More ideas about incircles will be posted here. Watch this space.
What can you see in this diagram?
Could you draw it? Could you draw a similar diagram with just 5 or 6 points around the outside? Try it?
How many lines are there in your diagrams? How many lines are there in the original diagram? Can you find a way of working out […]
SQUARES – GAME FOR TWO
Use a dotty grid and take it in turns to claim a point and mark it with your colour. The first person or team to get 4 of their markers at the vertices of a square wins the game.
PEOPLE MATHS – GAME FOR TWO TEAMS
A fence is built around a square field.
Suppose another fence is built exactly one metre longer so the path between the two fences is the same width along the edges of the field. How wide would this path be?
Would a mouse be able to run along it?
Could a farmer drive […]
Can you find all the sets of five positive whole numbers that have
a mean of 4
a median of 3
and a mode of 3?
One solution is 3, 3, 3 ,5 and 6 and there are several other solutions.
There are 11 solutions with a single […]
A fence is built around a square field.
Suppose another fence is built exactly one metre longer so the path between the two fences is the same width all the way round including at the corners of the field.
How wide would this path be?
Would a mouse be able to run along it? […]
A wire belt is tied tightly around the Earth at the equator. Suppose the belt is made exactly one metre longer and held around the Earth at the equator so that it is the same distance away from the Earth everywhere. Would a mouse be able to crawl under the new belt? How do […]
