Exercise 1
For the 2 questions below, use as many variables as you need.
- Draw the wheel of a Taxi cab at a center point of coordinates ( 100, 100 ). The hubcap is 30 pixels wide, the tire 50.
- Draw the second wheel of the Taxi cab with a center point horizontally 300 pixels away from the center, to the right.
Exercise 2
Same two questions as in Exercise 1, but you can only use 5 variables: P1, the original point (100, 100), h1, w1, the first hubcap and wheel, and h2, w2, for the second wheel.
