Question

Martin wants to use coordinate geometry to prove that the opposite sides of

Answer 1

The correct answer is option A which is the distance between A and D will be  AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$.

What is coordinate geometry?

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

The formula utilised to find the distance between two points is;-

X = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

We have the coordinates of the point A = (0, 0) and D is  (0, b).By applying the formula to find the distance between A and D.

AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$.

Therefore the correct answer is option A which is the distance between A and D will be  AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$.
