This example demonstrates the properties and construction of rectangles. Key mathematical concepts include geometry of rectangles and coordinate geometry. Using GeoGebra commands such as Segment, OrthogonalLine, and Point, the construction process of rectangles is dynamically illustrated. Suitable for students at middle school level and above to learn geometric construction and coordinate geometry.

  15. Angle(B, A, D) → β

AI Drawing Prompt Reference

Draw a rectangle by first placing two diagonal points A and B on the coordinate plane. Then, draw two sides through points A and B. Next, draw the perpendicular lines to these sides and find their intersection points C and D. Observe the angles γ, δ, α, and β, which are the interior angles of the rectangle.
