Answer:
Selection of all the true statements:
A: dilations always increase the length of line segments.
B: Dilations take perpendicular lines to perpendicular lines.
C: Dilations of an angle are congruent to the original angle.
F: Dilations of a triangle are similar to the original triangle
Step-by-step explanation:
Dilations are transformations that enlarge or reduce a figure from its original shape and size to another that a bigger or smaller. Dilations create similar figures because multiplying by the scale factor creates proportional sides while leaving the angle measure and the shape the same. This also implies that dilations of an angle are congruent to the original angle.
