Learning Outcomes:

The student will:

create, analyse, and describe designs using translations (slides), rotations (turns), and reflections (flips).

Translation Designs

Choose a color. Start drawing and watch the effect as 19 translation images are created. Switch colors to add extra color to your design.

Reflection Designs

Choose a color. Start drawing and watch the effect as 7 reflection images are created. Switch colors to add extra color to your design.

Rotation Designs

Choose a color. Start drawing and watch the effect as 4 rotation images are created. Switch colors to add extra color to your design.

use informal concepts of congruence to describe images after translations, rotations, and reflections.
Note: The following Flash object was designed for grade 9 science. It needs to be modified to meet the needs of this learning outcome.

State the coordinates of A, B, and C after the slide (R3, U4). Draw the image and compare the image to the original triangle.

draw designs, using ordered pairs, in all four quadrants of the coordinate grid together with translation and reflection images.

relate reflections to lines and planes of symmetry.

Draw in and label the line(s) of symmetry.
