Basic Constructions
This example demonstrates the altitudes of triangles. It involves key mathematical concepts such as the properties of triangles and geometric construction. By using GeoGebra commands to construct the altitudes of a triangle, students can visually understand the definition and properties of triangle altitudes. Suitable for middle school and above students for geometric construction.

AI Drawing Prompt Reference
Draw a triangle and construct its three altitudes. Start by marking three vertices and connecting them with line segments to form the triangle. Then, from each vertex, draw a perpendicular line to the opposite side, with the foot of the perpendicular lying on that side or its extension. The three perpendicular lines are the altitudes. The figure should clearly show the triangle, the three altitudes, and the feet of the perpendiculars, making it easy to observe that the altitudes intersect at a single point.
