Standard/s:
MGSE9-12.G.CO.9 Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment’s endpoints.

MGSE9-12.G.CO.10 Prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180 degrees; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point.

Learning Target:
Students can define basic Geometry vocabulary and identify common notations in Geometry.
Students use theorems to find values of angles.
Students will use theorems to find values of missing measures in triangles.

Success Criteria:
I can define basic Geometry vocabulary and identify common notations in Geometry.
I can use theorems and angle relationships to find missing measures of angles.
I can use theorems and characteristics of triangles to classify and find missing measures of triangles.
