Question

Quadrilateral A'B'C'D'is the result of rotating quadrilateral ABCD by 60° about the origin.

Choose all answers that apply

a. BC and B'C' are both parallel to the y-axis
b. <B and <B' have the same measures
c. D and D' have the same coordinates
d. none of the above

​

Answer 1

ONLY B IS A TRUE STATEMENT

Explanation:

were both doing rigid transformations: preserved properties on khan academy and i just got it right

Answer 2

a. No

b. Yes

c. No

Explanation:

a. For BC and B'C to both be parallel to the y-axis when BC is parallel to the y-axis the figure must be rotated by a multiple of 180 degrees.

b. When you rotate a figure none of the angles in the figure change.

c. For D and D' to have the same coordinates the figure must be rotated by 360.
