Answer:
D(-1,0)
Step-by-step explanation:
Plot points A(-3, 2), B(-1, 4), and C(1, 2) on the coordinate plane (see attached diagram).
Two sides AB and BC are of equal length and are perpendicular, because

If the quadrilateral ABCD has all sides perpendicular, then ABCD is a square. The diagonals of the square bisects each other. Find the coordinates of the point of intersection of these diagonals. This is the midpoint of segment AC:

If point O(-1,2) is the point of intersection of diagonals, then it is the midpoint of the diagonal BD. Find coordinates of point D:

Thus, D(-1,0)
Two triangles are similar if they are the same, except one is bigger and one is smaller. Also, their angles are all the same. A career that uses similar triangles could be a mathematician, or a math teacher. Both of these need to be able to understand simple concepts like similar triangles to teach to their victims.
C, 85% don’t hav an A
This is correct because it is the exact opposite therefor making it complimentary
