Hypotenuse-Leg Congruence Demo

This example demonstrates the Hypotenuse-Leg Congruence Theorem for right triangles, illustrating the conditions under which two right triangles are congruent. Key math concepts include triangle congruence criteria, properties of right triangles, and trigonometric functions (sine). The construction uses GeoGebra commands like Segment, OrthogonalLine, Point, Angle, Circle, and Intersect to build the triangles, measure angles and sides, and draw auxiliary circles to verify congruence. Suitable for high school geometry education and learning.
