Make a clinometer and use it to help you estimate the heights of tall objects.
On a clock the three hands - the second, minute and hour hands - are on the same axis. How often in a 24 hour day will the second hand be parallel to either of the two other hands?
Measure the two angles. What do you notice?
Construct two equilateral triangles on a straight line. There are two lengths that look the same - can you prove it?
Make an equilateral triangle by folding paper and use it to make patterns of your own.
Make five different quadrilaterals on a nine-point pegboard, without using the centre peg. Work out the angles in each quadrilateral you make. Now, what other relationships you can see?
Consider a watch face which has identical hands and identical marks for the hours. It is opposite to a mirror. When is the time as read direct and in the mirror exactly the same between 6 and 7?
How did the the rotation robot make these patterns?
