We are back on our normal schedule! Today was the last block of content for the transformation unit. Our focus today: finding lines of symmetry (reflection line) in a geometric figure, interpret rotational symmetry in a polygon (point symmetry) in terms of degrees of rotation before a figure coincides with its original (reading and investigation on pp 318-320 in textbook, problems 1-5 on p 320).
We also spent time figuring out if two figures are congruent by describing a sequence of rigid transformations (isometries) that could map one exactly on top of the other. The activity is attached below.
A grade was taken over HW #5 (answers on next blog post). Students viewed the 18 pt quiz or made it up.
There was an exit ticket done in class and turned in: a brief review of transformations in the coordinate plane.
Students received Test Topics and a review worksheet (HW #6). There is no textbook review for the test.
Transformation Unit Test - 60 pts, NEXT BLOCK!!
