Evidence of Understanding
 justify the minimum requirements that show two triangles are congruent

describe how a sequence of transformations demonstrates the mapping of corresponding sides for two congruent figures
 use notations to signify the corresponding parts

make conjectures about the minimum corresponding parts of the triangle needed to construct a congruent triangle
 experiment with constructions to support these claims
 give examples, non examples, or counterexamples about these claims
 use transformations of these parts to support their claim that the triangles are congruent

justify that when all corresponding sides of two triangles are congruent (SSS) there is sufficient evidence to show that these two triangles are congruent
 use tools to construct a copy of a given triangle using side measurements

justify that when two corresponding sides and the included angle are congruent (SAS) there is sufficient evidence to show that these two triangles are congruent
 use tools to construct a copy of a given triangle using two side measurements and the included angle
 establish the the minimum criteria necessary to prove two right triangles are congruent using the hypotenuse and a leg (HL)

justify that when two corresponding angles and the included side of two triangles are congruent (ASA) there is sufficient evidence to show that these two triangles are congruent
 use tools to construct a copy of a given triangle using two angle measurements and the included side
 justify why the angle has to be the included angle of the corresponding sides using constructions (SSA does not work)
