Angle Relationships and Triangles skills
Construct triangles and other geometric shapes with given conditions.
Find an unknown angle measure in a figure by writing and solving simple equations and using facts about supplementary, complementary, vertical, and adjacent angles.
Standards: 7.G.2, 7.G.5
Montana’s MAST is a state-specific through-year assessment built by New Meridian and aligned to Montana’s academic content standards, not a Smarter Balanced-style claims/targets framework. The math blueprints organize content into grade-level strands/testlets that map directly to CCSS-M-derived Montana standards.
The blueprint publishes a through-year design of 12 strands/testlets per grade, with 1 strand per testlet, 2 reporting attributes per strand, and 9–13 items per testlet. It also specifies approximate item-type and DOK distributions, but does not publish percentage weighting by domain in the captured blueprint text.
