Question

HELP FAST PLEASE.
Identify which transformations preserve just the line segment lengths, just the angle measures, or both the line segment lengths and angle measures of a transformed figure.

Select Line Segment Length, Angle Measure, or Both for each transformation below.

Answer 1

Answer:

• dilation: angle measure
• reflection: both
• rotation: both
• translation: both

Step-by-step explanation:

The "rigid" transformations, reflection, rotation, translation, preserve both angle and length measures.

Dilation changes lengths, so does not preserve that measure. However, it leaves angles unchanged.
