1 Geometry –Triangles: G 5.a; G 5.1, G 5.b; G 5.4; G 6.1,2,3,4

2 To assess prior knowledge: have students make circle maps to define the following: –Scalene –Isoceles –Equilateral –Obtuse –Acute –Right Isoceles triangle

3 Congruent Triangles Teacher would have Ss create Circle map to define Congruent triangles. They could then compare the different maps made (gallery walk – by posting on back wall of room) and decide what must be on every map for it to define Congruent triangles. A sample map is included. (A Circle map for Similar triangles is also included at end – but intended for a later lesson)

4 Congruent Triangles Non-Example Examples DefineWays to Prove CPCTC AAS SSS SAS AAA – similar but NOT congruent No SSA A set of points having the same size and shape 1:1 correspondence of equality Identical

5 Practice with Correspondence The following multi-flow maps are for practice with identifying triangle parts and correspondence After identifying relationships, (1/2: event - results) then students can pick out the items that cause congruence with rule – (1/2 : results/causes – event=congruence)
