I JUST NEED TO CONFIRM BEFORE TURNING IT IN A triangle has rotation symmetry that can take any of its vertices to any of its other vertices. Select all conclusions that we can reach from this.

a. A rotation of 120º will map the triangle to itself.
b. All sides of the triangle have the same length.
c. All angles of the triangle have the same measure.
d. A rotation of 60° will map the triangle to itself
