ABCD is a rhombus where A is the point (1, 2). a. Write the vectors AD (vector)

Question:

ABCD is a rhombus where A is the point (−1, −2).

a. Write the vectors A̅D̅_(vector) and D̅C̅_(vector) as column vectors.

b. Write the diagonals A̅C̅_(vector) and B̅D̅_(vector) as column vectors.

c. Use the properties of a parallelogram to find the coordinates of the point of intersection of the diagonals.

d. Find the gradients of the diagonals and hence verify that the diagonals are perpendicular.
