Geometry lesson about coordinate plane and the transformations of reflection and translation on the plane. Label the coordinates of the preimage and the image. Grab this set of pdf worksheets to become proficient in graphing the reflection of the shapes on a coordinate plane. Transformation worksheets translation, reflection, rotation. The points on the translated figure are indicated by the prime symbol to distinguish them from the original points. Move to the right if the number is positive or to the left if the number is negative. Lines of symmetry are examples of lines of reflection. A 90 rotation moves of the way around, which just means it moves one quadrant counterclockwise. How do we reflect geometric figures in a coordinate plane. When we rotate we always go in order of quadrant unless told otherwise. Reflections are isometric, but do not preserve orientation. We can perform transformations on a coordinate plane by changing the coordinates of the points on a figure. What are the coordinates of r s t if the figure is reflected over the xaxis and translated down two units. The collection of printable pdf coordinate planes on this page provide a number of different layouts that should fit the needs of.
A dilation is a transformation that moves each point on the original figure along a straight line drawn from a fixed point, called the center or point of dilation. Compare transformations that preserve distance and angle to those that do not e. Dilation produce figures that are the same shape as the original, but not the same. If the xcoordinate is 0,there is no movement along the xaxis.
Graph the image of the figure using the transformation given. A rotation turns a figure around a fixed point called the center of rotation. Identify the 4 basic transformations reflection, rotation, translation, dilation use correct notation to identify and label preimage and image points. Open ended draw a figure on the coordinate plane and then reflect it in the line y x. Coordinate geometry for transformations free worksheet. A figure is moved 5 units to the right and 4 units up. Graph your original shape on the coordinate grid on the. This cat face not counting the eyes and nose vertex points are 5, 1, 5, 5, 4, 4, 2, 4, 1, 5, 1, 1. Area of use values are in degrees based upon wgs 1984. Then,from the point on the xaxis,move parallel to the yaxis the number. Let the high school students translate each quadrilateral and graph the image on the. Revision worksheet check how well you have eased into the concept using this printable pdf worksheet. Well do two different transformations on this shape, resulting in three identical congruent kitties.
The description of a dilation must include the scale factor or ratio and the center of dilation. Geometry rotations explained 90, 180, 270, 360 youtube. Find the coordinates of the vertices of each figure after the given transformation. Translations in the coordinate plane pdf lesson video. Lets try some of this coordinate transformation stuff for ourselves. Transformations in the coordinate plane you identified translations, reflections, and rotations. From the origin,move along the xaxis the number of units given by the xcoordinate.
