A GCSE Maths video about congruence conditions for triangles. This video explores the SAS, SSS, ASA and RHS conditions, demonstrating how they can be identified to prove whether two triangles are ...
Investigate congruence by manipulating the parts (sides and angles) of a triangle. If you can create two different triangles with the same parts, then those parts do not prove congruence. Can you ...
"What is actually important about isosceles triangles?" "I remember that the base angles are equal, but I can't use that when it comes to problems." "They appear often in congruence and proofs, but I ...
