*Learning Goal: Build procedural fluency with using angles formed by transversals to solve problems and provide an opportunity to make free mistakes.*

# Classwork

- Estimation 180 – Day 112 (Andrew Stadel)
- Warm Up
- Go over Ungraded Formative Assessment
- Parallelogram Mazes… (Daniel Schneider)

# Finished Early?

# Standards:

**Common Core**- 8.G.A.5 – Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.

**TEKS**- G.5(A) – investigate patterns to make conjectures about geometric relationships, including angles formed by parallel lines cut by a transversal, criteria required for triangle congruence, special segments of triangles, diagonals of quadrilaterals, interior and exterior angles of polygons, and special segments and angles of circles choosing from a variety of tools
- G.6(A) – verify theorems about angles formed by the intersection of lines and line segments, including vertical angles, and angles formed by parallel lines cut by a transversal and prove equidistance between the endpoints of a segment and points on its perpendicular bisector and apply these relationships to solve problems
