Question

Use graph paper for this question. Take 1 cm = 1 unit on both the axes. Plot P(0, 5)
and Q(−2, 4). Point P is invariant when reflected in a certain axis.
(i) Name the axis.
(ii) Reflect Q on the x-axis to Q′, Q on the y-axis to Q′′ and Q in the origin to Q′′′.
(iii) Complete the figure PQQ′Q′′′Q′′ and write its geometrical name.

Answer 1

Step-by-step explanation:

(ii) The reflection of a point (x,y) about the y-axis will be (−x,y)

(iii) Coordinates :

′

(−5,−2),E

′

(−2,−5)

(iv) Th figure formed is an octagon

(v) x-axis or y-axi
