1. MORE CIRCLES AND STRAIGHT LINES
It gets more difficult to establish connections between circles and straight lines.

23.- Write in the values for the parameters of the circle and straight line so that the straight line goes through points A and B and B is the centre of the circle, which also passes through point A.

Write the values into the corresponding box "by hand", pressing the enter key after each one. Click the init button to start a new exercise. 

24.- Write in the values for the parameters of the circle and straight line so that the straight line goes through points A and B and AB is the diameter of the circle.
 
2. GAMES WITH CIRCLES
In this section you will look at how the positions of two or more circles relate to each other.

25.- Write in the values of the parameters of both circles whose centres points are A and B.

Write the values into the corresponding equations "by hand", pressing the enter key after each one.

Press the init button to start a new exercise.

26.- Write in the values of the parameters of both circles so that they are tangents and points A and B are the centres of the circles.
