Figure abcd is reflected across the y-axis. what are the coordinates of a' , b' , c' , and d' ? enter your answer in each box. a' ( , ) b' ( , ) c' ( , ) d' ( , ) coordinate plane. the horizontal axis ranges from negative 10 to 10 in increments of 1. the vertical axis ranges from negative 10 to 10 in increments of 1. quadrilateral a b c d has vertices a at negative 1 comma 4, b at negative 5 comma 8, c at negative 5 comma 4, and d at negative four comma 2.

Solution:

Let me explain you the meaning of term reflection ,When a shape is reflected across a line or either through X axis or Y axis the two shapes that is image and preimage are congruent means neither the shape , nor size of image changes.

The vertices of Quadrilateral A,B,C,D are (-1,4), (-5,8),(-5,4) ,(-4,2).

When we reflect Quadrilateral A B C D which lies in second quadrant , across y- axis we get reflected image in first Quadrant.

The coordinates of A'(1,4), B(5,8), C(5,4) and D(4,2).
