Examples
Lessons
- Drawing reflections on a grid - 1
Draw the mirror image after the shape is reflected across the mirror line (dotted line). - Drawing reflections on a grid - 2
Draw the reflections of both the lines and the points across the mirror line (dotted line). - Rotational symmetry
Does the picture have rotational symmetry? Yes or No. - Order of rotational symmetry
What is the order of rotational symmetry?- How many times does the shape look the same in one rotation?
- Rotating shapes 90°, 180°, 270° or 360°
Draw what it will look like if you rotate the shape: - Recognizing reflections and rotations of shapes
Circle the pairs that are correct.
