2014-03-12 08:53
This GeoGebra applet demonstrates how to construct a triangle on a geoboard and perform geometric analysis. Using polygon and angle commands, it dynamically displays the measurement of side lengths and interior angles. Combined with ruler elements and sequence commands, it helps learners intuitively understand the properties of isosceles and right triangles, as well as trigonometric applications,
