Answer» Answer: Given : A(5,4) , B(7,5) and C(-3,6) To Find : draw the IMAGE of the triangle ABC under reflection in the LINE y=3 Solution: A(5,4) , B(7,5) and C(-3,6) reflection in the line y=3 Hence X co-ordinate will remain same y - 3 = 3 - y' => y' = 6 - y New COORDINATE = ( x , 6 - y) A' = ( 5 , 2) B' = ( 7 , 1) C' = ( -3 , 0) invariant under this reflection => y' = y => y = 6 - y => 2y = 6 => y = 3 Any point on y = 3 For example ( 0 , 3) ( 2 , 3) , ( 3 , 3) are invariant Learn More: Point E with coordinates (5,7) is translated along a glide reflection to ... 58.
