In an equilateral triangle ABC, P is a point on edge AB, q is a point on edge AC, and AP = CQ. The distance between point a and the midpoint m of line PQ is 19 cm, then the distance between point P and point C is? (draw the picture by yourself, the original question is this.) Note: there is no need to draw a picture when answering You can't assume it
38cm, which can be calculated by a special method. (assume that PQ is the midpoint on both sides, and then replace it by equal quantity)
