Congruence

Students learn how to recognise and prove congruency using various angle properties and geometrical facts.  As learning progresses they consider the difference between similarity and congruence.
Differentiated Learning Objectives
• All students should be able to understand that congruent shapes have equal angles and lengths.
• Most students should be able to recognise SSS, SAS, ASA properties to prove congruency.
• Some students should be able to show congruency through reasoned algebraic proof.
