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

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
