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.
Explore, prove, and apply important properties of circles that have to do with things like arc length, radians, inscribed angles, and tangents.
Level up on all the skills in this unit and collect up to 1,000 Mastery points! Start Unit test. In analytic geometry, also known as coordinate geometry, we think about geometric objects on the coordinate plane.
