Students Will:
- Classify triangles by the lengths of their side lengths, and angle measures.
- Understand and apply the property that the sum of the angle measures of a triangle is 180 degrees.
- Understand and apply the properties of right, isosceles, and equilateral triangles.
- Understand that the sum of the length of any two sides of a triangle is greater than the length of the third side.

Upon completion of Unit 13:
- 5.G.B.3. Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
- 5.G.B.4. Classify two-dimensional figures in a hierarchy based on properties.
