AI Drawing Prompt Reference

Draw a parallelogram and a trapezoid to demonstrate the calculation of their areas and perimeters. Start by constructing the parallelogram with two pairs of parallel sides and locate the intersection of its diagonals. Then, create a trapezoid based on one side of the parallelogram, labeling key points. Finally, calculate and display the areas and perimeters of both shapes, using geometric transformations and matrix operations for assistance, suitable for high school students learning geometric properties and calculations.
