Reflections

Use a graph paper for this question (take \[2\] cm = \[1\] unit on both x and y axes). (i) Plot the following points: \[\mathbf{A}\text{ }\left( \mathbf{0},\text{ }\mathbf{4} \right),\text{ }\mathbf{B}\text{ }\left( \mathbf{2},\text{ }\mathbf{3} \right),\text{ }\mathbf{C}\text{ }\left( \mathbf{1},\text{ }\mathbf{1} \right)\text{ }\mathbf{and}\text{ }\mathbf{D}\text{ }\left( \mathbf{2},\text{ }\mathbf{0} \right)\].

(i) On graph: \[\mathbf{A}\text{ }\left( \mathbf{0},\text{ }\mathbf{4} \right),\text{ }\mathbf{B}\text{ }\left( \mathbf{2},\text{ }\mathbf{3} \right),\text{ }\mathbf{C}\text{ }\left(...

A triangle ABC lies in the co-ordinate plane. The co-ordinates of its vertices are A $\left( 2,3 \right)$, B $\left( 4,-4 \right)$and C $$$\left( 6,-7 \right)$. This triangle is reflected in the line y $=0$on to ΔA’B’C’. ΔA’B’C’ in then reflected in the origin onto ΔA”B”C”. Mention down the co-ordinates of ΔA’B’C’ and ΔA”B”C”.

In the question it is mentioned that, The co–ordinates of its vertices are A $\left( 2,3 \right)$, B $\left( 4,-4 \right)$ and C $\left( 6,-7 \right)$ Then, co-ordinates of ΔA’B’C’ under...
