What can be learned by placing a triangle, square, and circle together in a drawing?

Identification and comparison of different shapes

Placing a triangle, square, and circle together helps a learner notice that shapes have different outlines, corners, sides, and curves. Looking at them in one drawing makes comparison easier. This activity develops visual observation and helps students recognize basic geometric shapes. It is about understanding forms in art, not about the physical properties or price of the drawing materials.

The triangle can be identified by its three sides, the square by its four equal sides and corners, and the circle by its continuous curved boundary. Comparing these features shows how one shape differs from another and how several shapes can work together in a composition. Therefore, option A is correct; the other choices concern smell, sound, or cost, which are not learned by arranging shapes.
