What this review measures

Geometry builds a style of reasoning as much as a list of formulas. This expanded packet asks students to read and label diagrams, connect algebra to geometric relationships, justify conclusions, and retain the measurement and coordinate skills that transfer directly into Algebra 2 and later mathematics.

For parents and educators

Ask students to mark every given length, angle, and congruence relationship directly on the diagrams. Exact answers should stay in fraction, radical, or pi form unless a problem explicitly requests a decimal.

Every question below appears in the printable packet. Students should show their work and simplify answers unless directed otherwise.
