Reflection in X and Y Axes WORKSHEET
Suitable for Grades: 5th Grade, 8th Grade
CCSS: 5.G.A.1, 8.G.A.2
CCSS Description: Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).
Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

Reflection in X and Y Axes WORKSHEET DESCRIPTION
This worksheet on reflection is split into two sections.
Section A asks students to consider twelve separate sets of axes with an object and its reflected image. Students will then state whether each diagram represents a reflection in the x axis or the y axis.
In section B, learners will carry out twelve reflections of various objects in either the x or y axis as stated. Objects have horizontal, vertical and diagonal sides.
