how would you work out the centre of enlargenment of a transformed square, since all lines are equal?

Answer 1

To find the centre of enlargement for a transformed square, you will need to use at least two points on the square and their corresponding points on the transformed square. From there, you can use the formula:

Centre of Enlargement = Midpoint of Original Line / Midpoint of Transformed Line

Here are the steps to follow:

1. Choose two points on the original square and their corresponding points on the transformed square.
2. Find the midpoint of the line between the two original points and mark it on your graph.
3. Find the midpoint of the line between the two transformed points and mark it on your graph.
4. Draw a straight line connecting the two midpoints.
5. The point where this line intersects the original square is the centre of enlargement.

Note: If you have multiple pairs of corresponding points, you can use each pair to find the centre of enlargement and then take the average of the results for greater accuracy.
