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. [br][br]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.
Here's a big hint if you couldn't get there. The point of reflection is in quadrant II (which means above the x-axis and to the left of the y-axis) and is made of small numbers.
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 [url=https://www.youtube.com/watch?v=T8gkHJS4C54]this one[/url] to see one method.
