Nettet21. jan. 2024 · A transformation that uses a line that acts as a mirror, with an original figure ( preimage) reflected in the line to create a new figure ( image) is called a reflection. A reflection is sometimes called a flip or fold because the figure is flipped or folded over the line of reflection to create a new figure that is exactly the same size and shape.

Nettet15. jun. 2024 · There are three rigid transformations: translations, rotations and reflections. A translationis a transformation that moves every point in a figure the same distance in the same direction. A rotationis a transformation where a figure is turned around a fixed point to create an image. Nettet12. jun. 2024 · Triangle ABC has been reflected. The pre-image has vertices at. A(2, -1), B(4, 0), and C(3, -3). The image has a vertex A’ at (-1, 0). Where are B’ and C’ located and what is the equation for the line. of reflection? I know how to find the line of reflection, but to find the midpoints you would need more than one point. the gables thornham

NettetThis study explores the development of a pre-service teacher's mental structure from a motion view to a mapping view of geometric reflection. Many pre-service secondary mathematics teachers' (PTs) understand geometric reflection as a motion rather than a mapping of a domain containing points in a plane relative to a reflection line, which is … NettetA reflection is a type of transformation that takes each point in a figure and reflects it over a line. This reflection maps \triangle {ABC} AB C onto the blue triangle over the … NettetGeometry Reflection A reflection is an isometry, which means the original and image are congruent, that can be described as a “flip”. To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. the alfred motor inn
