Mark any three points on your paper that are not on one line. Label them A, B, C. Draw all possible lines going through pairs of these points. How many lines do you get? Name them. How many angles can you name using A, B, C? Write them down, and mark each of them with a curve as in Fig. 2.9.

When A, B, and C are marked as three non-collinear points, the lines AB, BC, and AC are formed by connecting each pair. These lines create three angles: ∠ABC, ∠BCA, and ∠CAB, with B, C, and A as respective vertices. To indicate these angles, mark their vertices and draw a curve inside each angle, making the geometric relationships between points clear and distinguishable.
