About this resource
What's inside this resource
Eleven reflection problems ask students to critique mislabeled reflection diagrams, reflect points, triangles, and multi-sided figures across a stated mirror line, describe transformations between a pre-image and image, find an unmarked mirror line on a coordinate grid, and combine reflection with rotation in a bonus multi-step problem. A full worked answer key is included as a second file, showing every reflected figure drawn in, the mirror lines located, and written descriptions such as 'Rotate figure A 180 degrees about Point T.' A short thank-you page from the creator, Nicole Maizelis, closes out the file. The problems increase in complexity from single-line reflections to combined reflection-and-rotation reasoning.

Teaching tips & learning objectives
Learning objectives
- Reflect points, line segments, and polygons across a given mirror line
- Identify errors in incorrectly drawn reflections
- Locate an unmarked mirror line between a figure and its reflected image
- Describe a transformation using correct vocabulary (reflection, rotation, translation) and units
Teaching tips
- Assign question 1 (spotting mistakes in mislabeled reflections) as a warm-up before students draw their own reflections
- Use the included answer key to model the bonus question as a class, since it requires combining reflection and rotation reasoning
- Have students label prime marks (A', B', C') consistently -- several answer-key notes call out missing or incorrect prime labeling as a common error
Skills covered
- Geometric reflection — students draw figures and images across given mirror lines on printed grids.
- Transformation analysis — students identify mistakes in reflections and name the transformation shown.
- Mirror-line reasoning — students locate an unmarked line of reflection between a figure and its image.
- Transformation composition — a later question relates two reflections to an equivalent rotation.
Good to know
Questions teachers ask about this resource
Does the worksheet require graph paper, or are the grids already printed on the page?
The grids are already printed on the worksheet pages -- figures and mirror lines are pre-drawn for students to reflect directly onto.
Is the bonus question graded the same way as the numbered questions, or is it optional?
Unclear from the file -- it is labeled 'BONUS' but no separate scoring guidance is given.
