Digital SAT Math
Lesson Plan
Similar triangles and proportional sides
Goals / Objectives
Determine whether two triangles are similar using Angle-Angle (AA) similarity
Identify corresponding sides and set up correct proportions between similar triangles
Solve proportions to find unknown side lengths
Recognize and apply similarity in overlapping, nested, and parallel-line configurations
Standards
"Use concepts and theorems relating to congruence and similarity of triangles to solve problems." "Determine which statements may be required to prove certain relationships or to satisfy a given theorem." "Apply knowledge that changing by a scale factor of k changes all lengths by a factor of k, but angle measures remain unchanged."
