*Side of triangle
*Side of triangle
*Use the file “1b. Measures in a triangle.ggb”. This file can be used to help students’ conception of triangle in a generalized manner. This file can be used to illustrate revise the points about vertically opposite angles, adjacent angles etc,. Help students identify the triangle. (Use the transaction notes for this file as needed)

*Ask the students to make another 3 triangles from the strings they have been given. Students should make a triangle in which all angles are acute and one in which one angle is obtuse. Use the following Geogebra file for types of triangles by angle.Have the students explore the types of angles in a triangle.

*Ask the students to make another set of two or three triangles with the strings they have been given. Is there anything you can say about the sides of the triangle? Show the Geogebra file called Types of triangle by sides.
