PPT-Dilations on the Coordinate Plane

Dilations on the Coordinate Plane Enlarging or reducing a figure is called a dilation A dilated figure is similar to the original figure The ratio of the new figure to the original is called a . Dilation. A . transformation in which a figure is enlarged or reduced with respect to a fixed point . C. called the center of dilation and a scale factor . k, . which is the ratio of lengths of the corresponding sides of the image and . GIS for Environmental Engineering. Spatial Referencing. We know we are somewhere there! but how can we know where we are ?. We are here!!!. Spatial Referencing. For that We need a reference. International Terrestrial Reference Frame(ITRF). Geodesy. - the shape of the earth and definition of earth datums. Map Projection. - the transformation of a curved earth to a flat map. Coordinate systems. - (x,y,z) coordinate systems for map data. Reflections on the Coordinate Plane. The undisturbed surface of a pond acts like a mirror and can provide the subject for beautiful photographs. Reflections on the Coordinate Plane. We call the waterline a “line of symmetry” because if the photo were folded at the waterline, the two halves would form a mirror image of each other. WITHOUT THE COORDINATE PLANE. To find the distance between two points, count the units between them.. There is another way to find the distance, without counting units.. First, we need to know the following things:. Vocabulary.

How can I use the coordinate plane to solve real-world and mathematical problems?. Lesson . 4.02. After completing this lesson, you will be able to say. :. I . can. identify and position pairs of rational numbers on a coordinate plane.. Plotting Points. In order to understand how to plot points on a coordinate plane, we must first recall how to locate integers on horizontal and vertical number line diagrams. Systems.
