New York State Regents Examinations
New York Regents Geometry — transformations, congruence, similarity, right triangles + trigonometry, circles, coordinate geometry, and measurement.
10 topics · 13 lessons · 141 practice questions
The vocabulary and angle rules that everything else in Geometry builds on — parallel lines, perpendicular lines, angle pairs, and the angle-sum/exterior-angle facts about triangles.
2 lessons · 5 practice questions
How figures move: translations, reflections, rotations, and dilations — what they preserve, what they change, and how to recognize them.
1 lesson · 17 practice questions
When two triangles are congruent: the five shortcuts (SSS, SAS, ASA, AAS, HL), how CPCTC lets you finish a proof, and the common Regents proof patterns.
1 lesson · 10 practice questions
When two triangles have the same shape but maybe different size: AA, SAS~, SSS~ shortcuts; side-splitter theorem; the midsegment theorem applied to similarity.
1 lesson · 11 practice questions
Pythagorean theorem, the special right triangles, the three trig ratios (sin, cos, tan), and the geometric-mean relationships from the altitude-on-hypotenuse setup.
1 lesson · 20 practice questions
What makes a parallelogram a rectangle, rhombus, or square — and the diagonal properties that pin down each shape.
1 lesson · 16 practice questions
Circle equations, central/inscribed angles, arc length and sector area, plus the rules for chords, tangents, and secants.
1 lesson · 19 practice questions
Distance, midpoint, slope; using coordinates to prove things about shapes; partition formulas for splitting a segment in a given ratio.
1 lesson · 17 practice questions
Volume formulas for prisms, cylinders, cones, pyramids, and spheres — plus density problems, solids of revolution, and 'how many bags do I need' applied questions.
2 lessons · 23 practice questions
Compass-and-straightedge constructions: bisecting segments and angles, copying segments and angles, perpendicular and parallel lines, and inscribed regular figures.
