Answer:
The correct option is;
The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects
Explanation:
With the assumption that that the question meant that ΔACD and ΔBCD are congruent, we have;
Segment
is congruent to segment
by Congruent Parts of Congruent Triangles are Congruent, CPCTC
Similarly, segment
is congruent to segment
by Congruent Parts of Congruent Triangles are Congruent, CPCTC
Therefore, the points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects
