Use these lessons to help your student(s) improve their understanding the properties of triangles, the parts of a triangle and the triangle theorems, as they prepare for related questions on the ISTEP+ Grade 7 Mathematics exam.

## ISTEP+ Grade 7 Math: Triangles - Chapter Summary

These lessons will help students review the parts, properties and theorems of triangles; thus, improving their skills solving mathematical problems with triangles. In them our expert instructors will help your student(s) prepare for questions on the Indiana Statewide Testing for Educational Progress Plus (ISTEP+) Grade 7 Mathematics exam that may ask about:

• The definition and properties of triangles
• Characteristics of equilateral, isosceles, scalene and right triangles
• Theorems and proofs of right triangles
• Using the properties of interior and exterior angles to solve problems
• Functions of medians, altitudes and angle bisectors of triangles
• SAS, ASA and SSS triangle congruence postulates
• Determining if triangles are congruent using the AAS theorem

After these lessons, have your student(s) take the lesson quizzes to discover topics from the lessons they don't understand. To help them improve their understanding of these topics, students may use the video tags to return to and study the parts of the lessons that explained them. Once a student has completed all the lessons and quizzes of this chapter, they can then test their overall understanding of the material presented in these lessons with the practice chapter exam.
