Which of the following methods is most suitable for teaching geometry?

Concept

Effective geometry teaching should connect abstract definitions with observable spatial relationships.

A demonstration uses models, diagrams, and instruments to make shapes, properties, and constructions visible before learners formalize them.

Application

Geometry depends on seeing how points, lines, angles, and figures relate. Demonstrating a figure or construction lets learners observe those relationships and connect the visual model with the underlying rule.

Contrast

• Play-based activity can support engagement, but without a planned geometric focus it may not systematically develop properties or constructions.

• Drill-and-practice strengthens recall and routine practice, but repetition alone does not build the initial visual-spatial concept.

• Formula-based teaching can support later calculation, but beginning with formulas can leave the meaning of shapes and relations abstract.

Result

Therefore, among the given methods, the demonstration method is the most suitable for teaching geometry.
