Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

The coordinates of $A$ are $\big($Gap 0.,Gap 1.$\big)$.

The coordinates of $B$ are $\big($Gap 2.,Gap 3.$\big)$.

The coordinates of $C$ are $\big($Gap 4.,Gap 5.$\big)$.

The coordinates of $D$ are $\big($Gap 6.,Gap 7.$\big)$.

Advice

The correct answers are obtained as follows.

The point $A$ is distance $\var{a}$ from the origin in the horizontal direction (positive is to the right and negative is to the left), so its $x$-coordinate is $\var{a}$.
The point $A$ is distance $\var{b}$ from the origin in the vertical direction (positive is upwards and negative is downwards), so its $y$-coordinate is $\var{b}$.
The point $B$ is distance $\var{c}$ from the origin in the horizontal direction (positive is to the right and negative is to the left), so its $x$-coordinate is $\var{c}$.
The point $B$ is distance $\var{d}$ from the origin in the vertical direction (positive is upwards and negative is downwards), so its $y$-coordinate is $\var{d}$.
The point $C$ is distance $\var{ee}$ from the origin in the horizontal direction (positive is to the right and negative is to the left), so its $x$-coordinate is $\var{ee}$.
The point $C$ is distance $\var{f}$ from the origin in the vertical direction (positive is upwards and negative is downwards), so its $y$-coordinate is $\var{f}$.
The point $D$ is distance $\var{g}$ from the origin in the horizontal direction (positive is to the right and negative is to the left), so its $x$-coordinate is $\var{g}$.
The point $D$ is distance $\var{h}$ from the origin in the vertical direction (positive is upwards and negative is downwards), so its $y$-coordinate is $\var{h}$.
