Question

How many lines of symmetry does the following figure have?

M

1 line of symmetry
2 lines of symmetry
3 lines of symmetry
An infinite number of lines of symmetry

A rotation is a type of transformation that can be defined as turning a figure about a fixed point with a change to the size and shape of the figure

True
False

When Point E (-9, 3) is rotated 270° counterclockwise about the origin, it becomes Point E’ (3, -9).

True
False

When Point E (6, 2) is rotated 90° counterclockwise about the origin, it becomes Point E’ (2, -6).

True
False

When Point E (7, -2) is rotated 90° counterclockwise about the origin, it becomes Point E’ (-2, -7).

True
False

What are the two types of dilations?

reduction and rotation
reflection and enlargement
rotation and translation
reduction and enlargement

Answer 1

the letter "M" has 1 line of symmetry

false, it does rotate about a fixed point, but it does not change size

false, it becomes (3,9)

false, it becomes (-2,6)

false, it becomes (2,7)

dialation is change of size
it doesn't include rotation
reflection is not change in size

answer is last one: reduction and enlargement
