Planes and point in a plane
Coplanar vs. skew lines of a rectangular prism
Given angles of a triangle, order the sides
Centroid question with algebra – find length of the line segment
Given a trapezoid find the missing side using Pythagorean theorem
Midsegment question – 3 midsegments in a triangle find a perimeter
Vocab: supplementary angles, linear pair, adjacent, vertical
Proof of 2 congruent triangles: which theorem can prove the congruency
If 2 triangles are congruent, what can you conclude about angles and sides
Parallel lines with transversal – find x.

Similar triangles – what it means about sides and angles.
Similar triangles – find the missing side
Similar triangles – find the perimeter
Similar triangles – find the area using the given ratio
Similar triangles – what properties hold true for the ratio, which measure do not maintain the ratio
Similar triangles – set up proportion different ways
Congruent triangles – which proof theorem can be used?
Find the missing angle of triangle within a triangle, which is the smallest or largest side.
Congruent triangles – properties that are true (corresponding sides and angles)
