Reflections: Interactive Activity and examples. Reflect across x axis, y axis, y=x , y=-x and other lines.
A reflection is a flip over a line. You can try reflecting some shapes about different mirror lines here: "How Do I Do It Myself?" Just approach it step-by-step. For each corner of the shape: 1. Measure from the point to the mirror line (must hit the mirror line at a right angle) 2. Measure the same distance again on the other side and place a dot.
REFLECTIONS: Reflections are a flip. The flip is performed over the “line of reflection.” Lines of symmetry are examples of lines of reflection. Reflections are isometric, but do not preserve orientation. Coordinate plane rules: Over the x-axis: (x, y) (x, –y) Over the y-axis: (x, y) (–x, y)
What is Reflection in Geometry, transformations on the coordinate plane, Examples and step by step solutions, Grade 9.
15 Ιουν 2022 · A reflection is an example of a transformation that takes a shape (called the preimage) and flips it across a line (called the line of reflection) to create a new shape (called the image). By examining the coordinates of the reflected image, you can determine the line of reflection.
Grade 9 Mathematics. Describe what happens for each of these transformations and give the rule: reflection in the x-axis. reflection about the line y = x. a point translated 3 units to the right and 4 units down. reflection about the y-axis. an enlargement by a factor of 2. a reduction by a factor of 3. . For the point Z (3; 5), give the point .
