Angle relationships: linear pair, supplementary, vertical, alternate interior, alternate exterior, same side interior, corresponding
Similarity: Use scale factors to make scale drawings and determine if drawings are to scale, begin dilations
Similarity: Use rigid transformations and dilations to show shapes are similar and prove triangles are similar by SSS~, SAS~, and AA~
Similarity: Use sine, cosine, and tangent to find side lengths and angle measures in right triangles
The Coordinate Plane: Use distance, slope, and midpoint to prove relationships and write equations of circles
3D visualization and measurement: Recognize the relationship between 3D figures and 2D slices of them. Find volume and surface area measurements of 3D figures.
Circles: Solve problems involving relationships between segments, lines and angles drawn in diagrams with circles
