Assess students' ability to recall and apply the standard side ratios and basic properties of 45-45-90 and 30-60-90 right triangles. Items require stating the canonical ratios, identifying legs and hypotenuse, computing missing side lengths from one given side (including simplified radical form), and recognizing these special triangles in figures. Scope: Grades 6–8, medium difficulty, focus on factual recall and straightforward computation.
