What will I learn?
This course provides a clear, hands-on guide to key concepts in triangles and circles. Learners will study exact definitions, congruence, similarity, triangle inequalities, and various area formulas. They will practise ruler-and-compass constructions, chord-radius links, and Thales’ theorem, while building strong algebra skills for sound geometric reasoning and effective problem solving.
Elevify advantages
