Question

Polygons ABCD and A′B′C′D′ are shown on the coordinate grid:




What set of transformations is performed on ABCD to form A′B′C′D′?

A translation 1 unit to the left followed by a 180-degree counterclockwise rotation about the origin
A translation 1 unit to the right followed by a 180-degree counterclockwise rotation about the origin
A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the right
A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left


i think its b but i don't know

Answer 1

A translation 1 unit to the left followed by a 180-degree counterclockwise rotation about the origin

Answer 2

So its the first one

Answer 3

thank you but how do you know if its clockwise or counterclockwise
