##### Description:

GEOM.2B Make conjectures about angles, lines, polygons, circles, and three-dimensional figures and determine the validity of the conjectures, choosing from a variety of approaches such as coordinate, transformational, or axiomatic.

GEOM.3D Use inductive reasoning by collecting information and finding patterns to formulate conjectures.

GEOM.5B Analyze numeric and geometric patterns to make generalizations about geometric properties, including properties of polygons, ratios in similar figures and solids, and angle relationships in polygons and
circles.

By the end of this unit, students will use a coordinate system, transformations, or axioms (postulates) to create algebraic or geometric models that validate conjectures about triangle properties including triangle inequality, This topic is from 5.5 in the Textbook and page 73 in the Interactive Notebook.
