AI Drawing Prompt Reference
Draw a horizontal line segment with a left endpoint and a right endpoint. Place a point above the segment, positioned to the left of the right endpoint and higher than the segment, forming a triangle. Drop a perpendicular line from this upper point to the segment, with the foot of the perpendicular landing on the segment, dividing it into two parts. Mark the foot as the midpoint of the segment, and draw the perpendicular bisector (a line through the midpoint perpendicular to the segment). The overall figure shows a triangle with an internal vertical auxiliary line, illustrating the geometric construction of the midpoint.
