Exploring Rotation 3

Question 6

This shape has been rotated. Find the point of reflection. If you get stuck, try moving the problem slider (in the top left) to problem 1 and playing around with the settings to get an idea of where the point of reflection might be. You could also use what you know about circles and the point of reflection - and draw some circles where you think the point might be. The point is a whole number coordinate pair, no decimals or fractions. Don't spend more than 5 minutes on this problem.

Don't worry if you didn't get there on your own, the process of trying to figure it out is making your brain smarter! I really wanted you to think about it more than just to get the right answer. If you want to know how one might do this without a grid to use, watch a video like this one to see one method.
