प्रश्न
Use graph sheet to Solution this question. Take 2 cm = 1 unit alogn both the axes.
- Plot A, B, C where A(0, 4), B(1, 1) and C(4, 0)
- Reflect A and B on the x-axis and name them as E and D respectively.
- Reflect B through the origion and name it F. Write down the coordinates of F.
- Reflect B and C on the y-axis and name them as H and G respectively.
- Join points A, B, C, D, E, F, G, H and A in order and name the closed figure formed.
उत्तर
- Reflexion of A(0, 4) on x-axis `->` E(0, –4)
and Reflection of B(1, 1) on x-axis `->` D(1, –1) - Reflection of B(1, 1) through origin `->` F(–1, –1)
- Reflexion of B on y-axis `->` H(–1, 1)
and Reflexion of C on y-axis `->` G(–4, 0) - The closed figure ABCDEFGHA is an octagon i.e. 8 sided star.
