The goal of this activity is to deepen students' understanding of the properties of isosceles triangles, deductive reasoning, and coordinate geometry.
At the end of a 90 minutes class, students should be able to:
- Calculate the midpoint, distance, perimeter, area, and slope by using the TI-Nspire calculator;
- Solve real world problems by applying their understanding of isosceles triangles, coordinate geometry, and deductive reasoning;
- Complete the group activity collaboratively.
Before the Activity
Load Isosceles2.tns file onto all the students' handhelds. The activity consists of a problem designed to be teacher directed with time for students to investigate and record their observations.
During the Activity
See directions in the attached teacher document.
