OpenStudy (devonhoward15):

OpenStudy (will.h):

Rotation 180 degrees having the rule: (x,y) --> (-x,-y) Let's apply that on the pointS we have P(1,-1) --> P'(-1,1) Q(3,-2) -->Q' (-3,2) R(3,-4) --> R'(-3,4)

jhonyy9 (jhonyy9):

in case of point (a). this is a rotation 180 degrees counter clock ways or inverse ?

OpenStudy (will.h):

Reflection across x axis (x,y) --> (x,-y) P(1,-1) --> P"(1,1) Q(3,-2) --> Q"(3,2) R(3,-4) --> (R"(3,4)

jhonyy9 (jhonyy9):

just bc. not is indifferent

OpenStudy (will.h):

It's about the origin jhony

OpenStudy (will.h):

Let me know if you have other questions I'll go help someone else
