hugo is writing a coordinate proof to show that the midpoints of a quadrilateral are the vertices of a parallelogram. he starts by assigning coordinates to the vertices of quadrilateral rstv and labeling the midpoints of the sides of the quadrilateral as a, b, c, and d. quadrilateral r s t v in a coordinate plane with vertex r at 0 comma 0, vertex s in the first quadrant at 2 a comma 2b, vertex t also in the first quadrant at 2 c comma 2 d, and vertex v on the positive side of the x-axis at 2 c comma 0. point a is between points r and s, point b is between points s and t, point c is between points t and v, and point d is between points r and v. enter the answers, in simplified form, in the boxes to complete the proof. the coordinates of point a are ( , ). the coordinates of point b are ( , ). the coordinates of point c are (2c, d) . the coordinates of point d are (c, 0) . the slope of both ab and dc is . the slope of both ad and bc is −bc−a . because both pairs of opposite sides are parallel, quadrilateral abcd is a parallelogram.

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?
