Priority Standard: Make formal geometric constructions with a variety of tools and methods
1. I can identify and use the properties of midsegments in triangles to find unknown measures.
2. I can identify and use the properties of
perpendicular bisectors (circumcenter) in triangles to find unknown
measures.
3. I can identify and use the properties angles bisectors (incenter) in triangles to find unknown measures.
4. I can identify and use the properties medians (centroid) in triangles to find unknown measures.
5. I can identify the altitudes (orthocenter) in
triangles.
6. I can use the relationships between sides and angles in triangles to find unknown measures.
7. I can use inequalities to make comparisons in two triangles
