What We Did Today:
Students started Problem 2.3: Minimum Measurement: Congruent Triangles II. Students developed understanding of using transformations to determine congruence of two triangles, with less than complete measurement information about the figures. Students did not perform transformations using tracing paper or other tools, but rather that they reason about why a subset of congruent criteria would guarantee that a transformation is possible or impossible, in all such cases.
Focus Question:
What is the smallest number of side and/or angle measurements needed to conclude two triangles are congruent?
Homework:
None.
