Compare the length of a segment of the preimage to the length of the corresponding segment of the image. the image, then the transformation is not a rigid motion. Therefore, use the protractor to check corresponding angles. If all angle measures are preserved, then check lengths.
When a figure is transformed with one or more rigid transformations, an image is created that is congruent to the original figure. Two figures are congruent if a sequence of rigid transformations will carry the first figure to the second figure.
So the above mentioned forms – reflection, rotation and translation are part of rigid motion. Dilation is non rigid motion.
The only choice that involves changing the size of a figure is letter a) dilation and as a result, creates two figures that are NOT congruent. The other three choices merely “move” a shape to a new location (i.e. rotated, translated, or reflected) and result in a congruent figure.
Non-congruent rectangles. These two polygons have matching sides equal but their matching angles are not equal and so they are not congruent. They are different shapes even though the sides are the same size. Non-congruent hexagons.
A dilation is not considered a rigid motion because it does not preserve the distance between points.
Dilations and rigid motions preserve angle measures. … Dilations do not preserve distance (side lengths) while rigid motions do.
A dilation is a type of transformation that enlarges or reduces a figure (called the preimage) to create a new figure (called the image). The scale factor, r, determines how much bigger or smaller the dilation image will be compared to the preimage.
A rigid motion is a transformation (of the plane) that “preserves distance”. In other words, if A is sent/mapped/transformed to A′ and B is sent to B′, then the distance between A and B (the length of segment AB) is the same as the distance between A′ and B′ (the length of segment A′B′).

Step-by-step explanation:
EFG is congruent to HJK, then HJK is congruent to EFG.
The SSA (or ASS) combination deals with two sides and the non-included angle. This combination is humorously referred to as the “Donkey Theorem”. SSA (or ASS) is NOT a universal method to prove triangles congruent since it cannot guarantee that the shapes of the triangles formed will always be the same.
Congruent means being exactly the same. When two line segments have the same length, they are congruent. When two figures have the same shape and size, they are congruent. … Similar figures are not congruent.
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. … Rays and lines cannot be congruent because they do not have both end points defined, and so have no definite length.
A non-congruent rectangle is a rectangle that is not identical to another rectangle. Its size, shape, or dimensions are different from the other rectangle. To compare two figures and detect changes in their shape/size, you will need to know the basic concepts of measurement.
Direct, proper or rigid motions are motions like translations and rotations that preserve the orientation of a chiral shape. Indirect, or improper motions are motions like reflections, glide reflections and Improper rotations that invert the orientation of a chiral shape.
In mathematics, a rigid transformation (also called Euclidean transformation or Euclidean isometry) is a geometric transformation of a Euclidean space that preserves the Euclidean distance between every pair of points. The rigid transformations include rotations, translations, reflections, or their combination.
