In a right angled triangle (90 degrees is one of the angles) the square of the long side is equal to the sum of the squares of the other two sides. The formula you will need to know for this activity is a^2+b^2=c^2 (a squared + b squared = c squared).
You have just picked up a ground ball at first base, and you see the other team's player running towards third base. How far do you have to throw the ball to get it from first base to third base to throw the runner out?
Hint: Using the segment tool to create a line might help visualize what you need to find out.
