Question

What is the line of reflection for triangle A B C and its image?

  1. x-axis
  2. y-axis
  3. y = x
  4. y = -x

hintHint:

General synopsis of reflection of a polygon with respect to x-axis.

The correct answer is: x-axis


    * In Geometry, a reflection is known as a flip. A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
    *It is a type of transformation that produces mirror image of the shape.
    Given That:

    >>> The points of reflection for the vertices of triangle A(-4,0);B(-3,3);C(-1,2) are A'(-4,0);B'(-3,-3);C'(-1,-2).
    >>>The point (a, b) is changed to (a, -b).
    >>>Therefore, the line of reflection becomes x-axis.

    From the graph, the line of reflection is x-axis.
