Learn high school geometry—transformations, congruence, similarity, trigonometry, analytic geometry, and more (aligned with Common Core standards).

Learn Geometry proof problem: midpoint Geometry proof problem: congruent segments Geometry proof problem: squared circle

Get ready for high school geometry! Learn the skills that will set you up for success in congruence, similarity, and triangle trigonometry; analytic geometry; conic sections; and circles and solid geometry.

Not only are right triangles cool in their own right (pun intended), they are the basis of very important ideas in analytic geometry (the distance between two points in space) and trigonometry.

Let's carefully define translations, reflections, rotations, and dilations. What stays the same when we transform figures?
