The lesson includes research-based strategies and strategic questions that prepare students for standardized assessments. In this lesson, students will identify special triangles and apply simple formulas to find unknown sides. In addition to the lesson, there are four pages of Independent Practice and four pages of Periodic Review with questions modeled after standardized assessments.
