Question

question 8 (multiple choice worth 1 points) (03.03r lc) if a figure has been dilated by a scale factor of 4, which statement explains how a translation can be used to prove the figures are similar using the aa similarity postulate? a translation can map one side onto another since dilations preserve side lengths of triangles. a translation can map one angle onto another since dilations preserve angle measures of triangles. a translation can map the center of a triangle onto another since dilations preserve the location of the center of triangles. a translation can map the vertices of one triangle onto another since dilations preserve the size of triangles.

Explanation:

Translation is a rigid transformation that preserves the shape and size of a figure. Dilation is a similarity transformation that changes the size but not the shape. For two triangles to be similar by AA (Angle - Angle) similarity postulate, we need to show that corresponding angles are equal. A translation can map one angle onto another because translations preserve angle measures.

Answer:

A translation can map one angle onto another since dilations preserve angle measures of triangles.
