Find the coordinate point for A that would make ABDC a rhombus. coordinate plane with points B 3 comma 4, and C at 2 comma 1, an
mixer [17]

Answer:

  • B.  (1, 3)

Step-by-step explanation:

We know the rhombus has perpendicular diagonals and the diagonals bisect each other.

The diagonals are AD and BC.

  • <em>Note. The points C and D should have swapped coordinates. This becomes ABDC.</em>

<u>The midpoint of BC is:</u>

  • ([3 + 2]/2,[4 + 1]/2) = (2.5, 2.5)

<u>Use A(x, y) and midpoint formula for the other diagonal AD:</u>

  • (x  + 4)/2 = 2.5 ⇒ x + 4 = 5 ⇒ x = 1
  • (y + 2)/2 = 2.5 ⇒ y + 2 = 5 ⇒ y = 3

Point A has coordinates (1, 3)

Correct choice is B
