This example demonstrates the basic properties of a rectangle. Key mathematical concepts include the definition of a rectangle, diagonal properties, and angle relationships. Using GeoGebra commands such as Segment, OrthogonalLine, and Point, the construction process of a rectangle can be dynamically shown. Suitable for middle school and above students to learn geometric construction and related properties.

AI Drawing Prompt Reference

Draw a rectangle with points A, B, C, and D, where AB and CD are parallel and equal, and AD and BC are parallel and equal. First, draw a line segment between points A and B, then draw two perpendicular lines from this segment to get points C and D. Next, draw the diagonals AC and BD, which intersect at point E and form four right angles. Measure and display the angles ∠DAB, ∠ABC, ∠BCD, and ∠CDA, as well as the lengths of diagonals AC and BD.
