Translation.
A reflection?
a transformation.
You get a curve. If you join them along the shortest [Euclidean] distance between them, you get a straight line.
The motion along a straight line is known as rectilinear motion.
A semicircle?
it is a translation
A semicircle is an example of a figure with one straight line. It is a circle that has been split along the diameter.
you guys dont know me eitherA translationTranslationA translation is movement of a figure to a new position along a straight line.
to slide or move a figure to a new position along a striaght line
It depends on the form of transformation.
A reflection?
A reflection.
Its like flipping it's a reflection
a transformation.
You get a curve. If you join them along the shortest [Euclidean] distance between them, you get a straight line.
a closed figure with all straight line segments is called a polygon.
A plane figure cannot be bounded by only one straight line. If the shape is bounded by lines which are not straight or by several straight lines the answer will depend on exactly what these are.
