6. (02.03 MC) Triangle ABC is shown. A is at negative 5, 4. B is at negative 7, 2. C is at negative 2, 3. If triangle ABC is rotated 180 degrees, reflected over the y-axis, and reflected over the x-axis, where will point A' lie? (5 points) (5, −4) (4, −5) (−4, 5) (−5, 4)

  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.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
