It clearly needs a rotation at least 90 degrees maybe 180 and then a translation, but I am not seeing exactly how to do it.
use a protractor
I agree with retired
I can help you more hang on
ok so the two triangle have the same shape so what you first do to make them 'align' with each other consider a rotation maybe choose point C how much would you rotate by until the triangles aligned ?
So take point C(-1,3) If we preform a counterclockwise rotation (x,y) --> (-y,x) so after rotation is would be (-3,-1) and now we will have to translate it using the rule 2 moves right (X+2,y) --> which would get the point (-3,-1) to C'(-1,-1) So the transformations were a counterclockwise 90 degree rotation and a translation of (x+2,y)
Well - that rotates about the origin You could alternatively rotate about point C (i.e. point c does not move) Then translate DOWN 4 i.e. y >y-4
