Question

2 multiple choice 1 point
a transformation is the movement of a figure that doesnt change the ________ of that figure.
none of the above
size and color
size and shape
weight and height

3 multiple choice 1 point
another word for reflection is ________.
swap
lift
flip
slide

4 multiple answer 1 point
which figure(s) have 4 lines of symmetry?

Explanation:

Analyze Question 2

A geometric transformation maps a figure onto a new position. Rigid transformations (isometries) preserve size and shape, which is the standard definition referred to in introductory geometry.

$$ \text{Preserved properties} = \text{size and shape} $$

Analyze Question 3

A reflection is a transformation that flips a figure over a line of reflection.

$$ \text{Reflection} \equiv \text{flip} $$

Analyze Question 4

• The crescent moon shape has only 1 line of symmetry (horizontal line through its center).
• The orange rhombus shown is a square rotated by 45 degrees. A square has 4 lines of symmetry (2 diagonal, 1 horizontal, 1 vertical).

$$ \text{Lines of symmetry (crescent)} = 1 $$

$$ \text{Lines of symmetry (square/rhombus)} = 4 $$

Answer:

Question 2

• None of the above
• size and color
• size and shape (Correct answer)
• weight and height

Question 3

• swap
• lift
• flip (Correct answer)
• slide

Question 4

• Crescent moon
• Orange square/rhombus (Correct answer)
