Stein - Math 8 Plus - 3.7.17

What We Did Today:

Students completed Problem 2.2: Supporting the World: Congruent Triangles I. Students used measurement of sides and angles to decide if pairs of triangles were congruent. If the triangles were congruent, students needed to identify corresponding vertices as well as give a sequence of transformations that would make the figures overlap. Notes are available at http://norupstein.weebly.com/math-8-plus-blog

Focus Question:

How much information do you need to decide that two triangles are probably congruent or not congruent? How do you go about planning transformations that 'move' one triangle onto another?

Homework:

None.
