I am needing help explaining to my 10 year old cousin about congruent figures and motions - he has to describe how four turns can put a figure in its original position. Many thanks!

Well, tell him this. A '360' is a skateboarder turning around in a circle in the air, right? tell him to imagine this skateboarder turning in a circle, but slice his movement into 4 sections, so each part of a turn looks like a quarter of a circle. Each section is one turn in geometry. If you turn it 4 times, like the skateboarder, you get back to its regular position, like the skate boarder when he lands back on the ground. Hope this helps.
