Answer:
C, E, F
Step-by-step explanation:
A is false because dilations can not only increase the length of line segments, but also decrease the length of line segments.
B is a true statement.
C is true because when angles undergo dilations, their "size" does not change.
D is false because dilations do not increase the measures of angles.
E is false because a triangle that underwent a dilation becomes similar, not congruent.
F is true because of E's reasoning.
