Question

figures that are similar will always have rotational symmetry.
true
false

9 multiple answer 1 point
what are the 3 types of transformations?
reflection
translation
congruent
symmetry
rotations
swapping

10 fill in the blank 1 point
how many lines of symmetry does this shape have?

Explanation:

Analyze similarity and rotational symmetry

$$ \text{Similarity does not imply rotational symmetry. For example, any two non-symmetric scalene triangles are similar but have no rotational symmetry.} $$

Identify the three types of rigid transformations

$$ \text{The standard rigid transformations are: Reflection, Translation, and Rotation.} $$

Determine lines of symmetry for the red cross shape

$$ \text{A symmetric cross (with equal arms) has 4 lines of symmetry: 1 vertical, 1 horizontal, and 2 diagonal.} $$
