Similar figures are figures of the same shape but different (or same) size.
Thus, they look the same, but one is bigger than the other by a scale factor.
Congruent figures are figures of the same shape AND same size.
They can be mapped onto each other using any type of transformation (besides dilations).
Similar figures can be dilated.

Answer:
The value of the expression is 382
Step-by-step explanation:
x = 77 and the expression given is 5x - 3
5x - 3
input the given
