Triangle Theorems
This example demonstrates the properties of an isosceles triangle, allowing students to discover the Isosceles Triangle Theorem and related theorems without angle measures. It involves core concepts like isosceles triangles, triangles, geometric mean, scatter plot, trapezoid, right triangles, and variance. Construction uses GeoGebra commands such as Circle, Intersect, Segment, Angle, Rotate, and Midpoint. Suitable for high school mathematics education to explore geometric theorems and properties.

AI Drawing Prompt Reference
Draw an isosceles triangle ABC with A and C as the base vertices and B as the apex. Use rotations and dilations to construct the triangle's medians, altitudes, angle bisectors, and form a complex shape with multiple arcs and segments.
