1. Angle ABC is taken by a dilation with center P and scale factor 3 to angle A'B'C'. The measure of angle ABC is 21°. What is the measure of angle A'B'C'?

 

Do not include units (degrees) in your answer.

 

 

5. A polygon has a perimeter of 18 units. It is dilated with a scale factor of 3/2. What is the perimeter of its image?

1.  Not sure about this  one, GM......but  the dilation of an angle  only changes  the length of each of the "arms"  of the angle, but does  not change  its  measure

 

So A'B'C'  also  measures  21    [ I think ]

 

 

2.  New perimeter =  scale factor x old perimeter  = (3/2) * 18 =  27 units
