@sleepyjess can you please help ?

sleepyjess · Answer

do you know what each of these are?

anonymous · Answer

Dilation: A transformation in which a polygon is enlarged or reduced by a given factor around a given center point. 
Rotation: moving of a figure through a given number of degrees, about a fixed point
Reflection: A transformation in which a geometric figure is reflected across a line, creating a mirror image.
Translation: rigid motion, meaning an object changes its position but not its size or shape

not the best drawing but pretend it is correct :-)

anonymous · Answer

isnt that a translation ? @sleepyjess

sleepyjess · Answer

no that would be rotating the triangle
this is translation

translation just means that it moves over
