Sample Lesson Plan using Geogebra
In this lesson, Geogebra was used as an exploratory tool to enable deductive reasoning among learners. The learners will be given the chance to observe through manipulating the STEM Tool and writing down their observations.
After the observation, the learners will be asked to formulate the relationship among angles and arcs given.
Below is the embedded Geogebra manipulative that the students will be exploring.

Steps:
You may download the application (Geogebra 6) or work online. Visit geogebra.org.
Prepare your Geogebra worksheet using the “Geometry” feature.
Create a circle.
Create additional points in the circle using the tool “Point on Object.” Perform drag test to check if the point is on the circle.
Using the points, create a central angle using the tool “Segment.” Create an inscribed angle that share a common intercepted arc as the central angle.
Measure the angles formed by both angles.
Drag the points and observe the angle measurements.
