a dilation about the origin with scale factor 1.5 transformed triangle xyz into triangle x'y'z'. all three sides of triangle x'y'z' must be to the corresponding sides in triangle xyz and the corresponding angles are .
parallel
congruent
perpendicular
proportional

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
