  5. Distance(C, f) → g

AI Drawing Prompt Reference

Draw a triangle using three line segments connecting three points. Calculate its area by drawing perpendicular lines from one vertex to the opposite side, marking the foot of the perpendicular. Measure the length of the perpendicular (height) and the base. Calculate the area using the formula: area = (base * height) / 2, and display the result.
The prompt above was compiled from the original drawing commands and is for reference only.
