Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider two triangles ABC and DEF such that sides AB = 5 cm, BC = 6 cm, and AC = 7 cm, while sides DE = 5 cm and EF = 6 cm. If triangle DEF has an angle equal to angle C, are the triangles congruent, and why?

💡 Hint: Examine each triangle side’s relationship with the corresponding angle.

Challenge 2 Hard

You have triangles GHI and JKL, where angle G = 60°, angle H = 80°, and side GH = 7 cm. Triangle JKL has angles of 60° and 80° as well. Can you analyze if they are congruent?

💡 Hint: Consider if equal angles imply potential side congruency.
