# Q1,W7: September 24-28

Teacher Kristin Andreason Geometry Honors 8 Seven Unit Two (A): Triangle Congruence and Proofs
Standard(s) Taught
• MAFS.912.G-CO.1.2:  Represent transformations in the plane, describe transformations as functions that take points in the plane as inputs and give other points as outputs, compare transformations that preserve distance and angle to those that do not.
• MAFS.912.G-CO.1.4:  Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments.
• MAFS.912.G-CO.1.5:  Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using graph paper.
Learning Targets and Learning Criteria
• Students will be able to use tools to precisely copy a segment, an angle, a segment bisector, an angle bisector, a line perpendicular to a line, and a line parallel to a line.
• Students will understand how to draw transformations of reflections, rotations, translations, and dilations.
• Students will be able to find the coordinates for the image of a figure when a transformation is applied to the pre-image.
• Students will be able to distinguish between transformations that are rigid and those that are not.
• Students will be able to define pre-image and image, using correct notation.
• Students will be able to model reflections, translations, and rotations by connecting any point on the pre-image to its corresponding point on the new image.
• Students will be able to draw a specific transformation when given a geometric figure and a rotation, reflection, translation, or dilation.
Classroom Activities

Monday/Tuesday:

• Students will finish the Transformations summary page and I will show them some examples of each type of transformation
• Students will then begin to copy the transformations notes in their ISN on page 12

Wednesday:

• Students will continue the transformations notes on page 12 of their ISN and do some examples on graph paper

Thursday/Friday:

• Students will finish up the last little bit of notes on transformations
• Students will then do the Transformations Cube Activity where they will roll a cube and then translate a figure according to what the cube says
Assignments Due
• ISN notes on page 12 should be completed by Friday, September 28.
