AIM: How can we practice geometric concepts for our midterm?
HW: Prepare for the midterm
Announcements: High School midterms will take place Tuesday and Wednesday, January 17 & 18. Please begin reviewing now.
Basic elements of geometry (point, line, plane, ray, angle, etc.)
Parallel lines cut by transversal
Graphing parallel/perpendicular lines
Triangle congruence shortcuts (and proofs)
Properties of quadrilaterals
Similarity (&triangle shortcuts)/dilations
Right triangle similarity
Do Now: The line y=2x-4 is dilated by a scale factor of 3/2 and centered at the origin. Write the equation of the line that is the image of the line after the dilation.
Classwork: Students worked on a midterm practice exam. Opportunities for individualized instruction were available at request.
