Today was the last block of content for the transformation unit. If you were absent, you need to read this post carefully and do what we did in class as well as the homework. The Unit Test is the next block!!
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). (New textbook pages.)
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 #4 (answers on next blog post). The 18 pt quiz was returned.
We did an 8 question Multiple Choice formative assessment in class today - 8 pts. If you missed class, it will not be made up.
Students received Test Topics and a review worksheet (HW #5). There is no textbook review for the test. (attached below)
Transformation Unit Test - 60 pts, NEXT BLOCK!!
Vocabulary Graphic Organizer attached below.
