Geometry Construction and Rotation Exploration from Wuhan No.2 High School 2018
2020-05-28 04:51
This applet explores Question 23(3) from Wuhan No.2 High School's 2018 exam. Using GeoGebra, it combines basic objects like segments, angles, and circles with transformations like rotation to visualize complex geometric relationships. It helps students understand rotation properties, auxiliary lines, and locus problems, enhancing geometric intuition.
