#### Question

Use graph paper for this question) (4)
A(0, 3), B(3, −2) and O(0, 0) are the vertices of triangle ABO.

(1) Plot the triangle on a graph sheet taking 2 cm = 1 unit on both the axes.1
(2) Plot D the reflection of B in the Y-axis, and write its coordinates.
(3) Give the geometrical name of the figure ABOD.
(4) Write the equation of the line of symmetry of the figure ABOD.

#### Solution

1) ΔAOB is shown in the graph.

2) the reflection of B in Y-axis is given by D (−3, −2)

3) figure ABOD is a tetrahedron 4) Equation of line of symmetry of figure ABOD is x = 0, i.e. y-axis
