Web7. dec 2016 · First, here's the midpoint of line segment KK': Plug these coordinates into the equation y = 2 x – 4 to see whether they work. Because 12 = 2 (8) – 4, the midpoint of line segment KK' lies on the reflecting line. Now get the slope of line segment KK': This is the desired slope, so everything's copasetic for K and K'.

They will also be able to reflect images of WebA reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure. The reflected image should have the same shape and size, but the image faces in the ...
WebA reflection is a shape or pattern that is reflected across a line of symmetry. It has the same size and shape as the original but is flipped. In these worksheets, students identify and draw reflections (flips) of shapes. Identifying reflections: …
