Tenth graders investigate dilations and explore the dilation transformation before investigating the properties of a dilation using Cabri Jr. Young scholars extend the concept of dilatation to the coordinate plane.

When is the distance formula not accurate? Referencing a map of the school, pairs determine the walking distance between two locations. Creating coordinates for each location, pupils determine the distance between the two points and...

Learners solve geometric problems with algebra and graphing in this lesson. They will prove the bisectors theorem using the Cabri Jr. application, which requires Cabri on their TI.

Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.

Students analyze midsegments of triangles in this instructional activity. They use Cabri Jr. software to observe the relationships between interior angles and midsegments of triangles. Specific instructions for creating this...

This activity operates in one of two modes: auto draw and create shape mode, allowing you to explore relationships between area and perimeter.

Explore finding and measuring perimeter of figures.
