Answer:
Dilations of a triangle are similar to the original triangle.
Dilations of a polygon always keep angle measures the same.
Explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Dilation is a type of transformation that enlarges or reduces an object thereby producing an image which has the same shape but a different size as the object. When dilation is done the image produced is similar and has the same angle measures as the original object.
Dilations of a triangle are similar to the original triangle.
Dilations of a polygon always keep angle measures the same.
Dilations of a triangle are not congruent but similar to the original triangle.
Dilations does not increase the measure of angles, instead it keeps the angle measure.
Dilations does not always increase the length of line segments, it an either increase or decrease the length.
