Question

Use graph paper for this question:

• A. Plot the points $A(-4,2)$ and $B(2,4)$
• B. $A^1$ is the image of $A$ when reflected in the line $x=0$. Write the co-ordinates of $A^1$.
• C. $B^1$ is the image of $B$ when reflected in the line $A{A}^1$. Write the co-ordinates of $B^1$.
• D. Write the geometrical name of the figure $AB{A}^1{B}^1$

Answer 1

The correct option is A Plot the points $A(-4,2)$ and $B(2,4)$

1) plot points $A(-4,2)andB(2,4)$

2) A' image of A in $x=0$ $\therefore A^{\prime }\equiv (4,2)$

3) B' image of B in AA' $\therefore B^{\prime }=(2,0)$

4) shape of ABA'B' is shaped quadrilateral.
