Move point Fto the origin, (0, 0), so the equation of EF is y = x. Now record the coordinates of the vertices of the polygon ABCD. What are the coordinates of the vertices of the reflected polygon AFFBEECEEDEF where EF is the line of reflection? Enter the coordinates in the table.

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Measures of the angle of r, 31 s (x+4) t (3x+9)
