Question

Triangle ABC is on a coordinate plane.

If its rotated 180 degrees around a specific point to create A'B'C'

Which characteristics are true for both the original triangle and the triangle's image?

Question 11 options:

The measures of

The coordinates of B' will be the same as B.


The coordinates of A' will be the same as A.


The Area of ABC will be the same as A'B'C'


The perimeter of ABC will be the same for A'B'C'


The length of segment AB will be the same as Segment A'B'

Answer 1

The last 3 choices are correct

Explanation:

A rotation of 180 degrees has the rule (x,y) →(-x,y) , so the coordinates will not be the same. The shape's size doesn't change.
