### Constructing polygons with equal area

The power of GeoGebra lies not only for demonstrating a concept but more so for creating a situation where students are made to think, solve problems, and reason mathematically. Here is a sample lesson on how this can be done. The lesson involves the concept of area of triangles and constructing parallel lines applied to problems…

### Geometric relations – angles made by transversal

Geometry is a natural area of mathematics for which students should develop reasoning and justification skills and their appreciation of the logico-deductive part of mathematics that build across the grades. Learning tasks therefore should be so designed so that the focus of the learning is on the development of these skills as well and not…

### Problem on proving perpendicular segments

This problem is a model created to solve the problem posed in the lesson Collapsible. In the figure CF = FB = FE. If C is moved along CB, describe the paths of F and E. Explain or prove that they are so. This problem can be explored using GeoGebra applet.  Click this link to explore…
