Question

A' and B' are images of A (-3, 5) and B(-5, 3) respectively when reflected in the y-axis. The points form a quadrilateral AA'B'B. AB' & BA' are equal in length.

• A. True
• B. False

Answer 1

The correct option is A

True

A(-3, 5) is reflection in the y - axis, So $A^{\prime }\equiv (3,5)$

B (-5, 3) is reflection in the y - axis, So $B^{\prime }\equiv (5,3)$

SInce AA'B'B is an isoceles trapizium, the diagonals will be equal, hence AB' will be equal to A'B.
