$200 Question
Potpourri
Does the figure have line
symmetry? If so, draw all lines of
symmetry.
$200 Answer
Potpourri
Yes, 2 lines of symmetry.
$400 Question
Potpourri
Does the figure have rotational
symmetry? If so, give the angle of
rotational symmetry and the order
of symmetry.
$400 Answer
Potpourri
Yes,
Angle of rotation = 72°,
Order = 5
$600 Question
Potpourri
A translation can be
interpreted as successive
reflections across two lines.
Tell what relationship the lines
must have for this to be true.
$600 Answer
Potpourri
They must be
parallel
