Describe and perform combinations of translations, reflections, and rotations up to 360° on a grid, and predict the results
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
Sample: the first question, solved
If a shape is reflected over the y-axis, does its size change?
📘 Worked solution
✓No - a reflection is a rigid transformation, so it flips orientation but keeps size and shape exactly the same.
And one from the hard end
Design a combined transformation using a reflection, a rotation, and a translation on a triangle with vertices (2,0), (5,0), (2,4), and explain what stays invariant (unchanged) throughout every step.
