Choose one of the polygons that are similar to Polygon A, and describe a sequence of transformations that take Polygon A to the selected polygon.

E is similar, a rotation and translation can take polygon A to polygon E.

Step-by-step explanation:

a rotation 90 degrees counter clockwise around point r and a translation 4 down and 9 right will take plygon A to E.

Step-by-step explanation:

so its b,c and e

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
