On a graph paper plot the triangle ABC whose vertices are A(5,4) ,B(7,5) and C(-3,6). on the same graph , draw the image of the triangle ABC under reflection in the line y= 3 . Mark any two points which are invariant under reflection and also write their coordinates.. Kindly tell me which are the invariant points here and why ? (I have reflected the triangle.) |
