Graph the original triangle, and from there use the equations to graph the other triangles.
Translation- (x,y)-->(x+ a number,y+ a number)
Dilation- (x,y)-->(2x,2y)
Reflection across x-axis- (x,y)-->(x,-y)
Reflection across y-axis- (x,y)-->(-x,y)
-x just means opposite of x
180° rotation- (x,y)-->(-x,-y)
