Vocabulary - this is important!
Notation - angles, segments, lines, rays, arcs, measure of an angle or arc, when to use congruence vs equals
Angles - complementary, supplementary, vertical, linear pair, acure, obtuse, right, etc.
Parallel lines with transversals - angles formed and their relationships
Triangles - types, congruency theorems similarity theorems, special lines midsegments and the concurrencies, incenter, circumcenter, etc.
Trigonometry - right triangle side relationships
Quadrilaterals - trapezoids, parallelograms, cyclic quadrilaterals
Polygons - concave, convex, interior and exterior angles
Proofs - to fill in blank flow-chart proofs, one write from scratch proof
Circles - inscribed angles, central angles, secant line theorems, arc measure and arc length, tangent lines
Perimeter, area and volume - triangles, special quadrilaterals, compound shapes, prisms, pyramids and cones, spheres
Coordinate plane - slope, parallel slopes, perpendicular slopes, equation of a line, length of a segment
