WA High School Geometry Curriculum
Give your teen the support they need to keep up with Washington's Geometry course - lessons and practice problems covering every strand, from rigid motions to trigonometry and volume.
About High School Washington Geometry
Washington follows the Washington State K-12 Learning Standards, organized around Big Ideas connecting geometric reasoning, proof, and modeling. This Geometry course covers congruence and rigid motions, similarity and trigonometry, circles, expressing geometric properties with equations, geometric measurement and dimension, and modeling with geometry. StudyPug provides step-by-step video lessons and practice problems aligned to every strand so students can move at their own pace.
- Strands: congruence, similarity and trigonometry, circles, geometric properties with equations, measurement and dimension, and modeling
- Step-by-step video lessons for every Geometry topic
- Practice problems with instant feedback after each lesson
- Fully aligned to Washington State K-12 Learning Standards for High School Geometry

WA High School Geometry Topics
- Congruence and rigid motions: precise definitions, transformations in the plane, rotations, reflections, translations, triangle congruence criteria (ASA, SAS, SSS), and formal geometric constructions including figures inscribed in circles.
- Similarity, proof, and trigonometry: similarity transformations, the AA criterion, triangle theorems, trigonometric ratios for acute angles, the relationship between sine and cosine of complementary angles, and applying the Pythagorean Theorem to real-world problems.
- Circles: inscribed angles, radii, chords, arc length, radian measure, sector area, tangent lines, and properties of angles in cyclic quadrilaterals.
- Expressing geometric properties with equations: equations of circles and parabolas, equations of ellipses and hyperbolas, slope criteria for parallel and perpendicular lines, partitioning a directed line segment, and using coordinates to compute perimeters and areas.
- Geometric measurement and dimension: formulas for circumference, area of a circle, and volumes of cylinders, pyramids, cones, and spheres; cross-sections of three-dimensional objects.
- Modeling with geometry: describing objects with geometric shapes and measures, density based on area and volume, and applying geometric methods to design problems.
How StudyPug Helps WA High School Geometry Students
When a student gets stuck on a proof or a trigonometry problem, StudyPug lets them pull up a focused video lesson on that exact concept - whether it is the definition of congruence in terms of rigid motions or deriving the equation of a circle using the Pythagorean Theorem. Each lesson is followed by practice problems with instant feedback and step-by-step video solutions, so the student sees not just the answer but the full reasoning.
Because every topic is mapped to Washington State K-12 Learning Standards, a student preparing for class, catching up after an absence, or getting ahead before a test can move directly to the strand that matters most without wading through unrelated material.
Aligned to WA High School Geometry Curriculum
StudyPug Geometry content is built around the Washington State K-12 Learning Standards, covering every strand from congruence and rigid motions through circles, coordinate geometry proofs, and geometric modeling - so what students practice on StudyPug matches exactly what they are expected to know in a Washington high school Geometry class.
