Finding Angles and Tracing a Path with a Robot
Problem Statement:
The pre-placed block will show a right triangle on the grid. Find all the angles and lengths of the triangle and trace the triangle with the robot, and end with the robot in it's starting position and angle, ready to trace the triangle again.
