Students reflect figures over the x- and y-axes, rotate figures 90°, 180°, and 270° counterclockwise about the origin, and write rules for each reflection and rotation.
In Problem 1, students investigate reflections. Students will explore the triangle and its reflection to discover that the x-values of pre-image and image points are equal, while the y values are opposites.
In Problem 2, students will explore rotations of a quadrilateral.ABCD is drawn in Quadrant 1. Students find and record the coordinates of both figures and discover the properties of rotated figures.
