Classifying Quadrilaterals

This week, we started our geometry unit.  We've been learning attributes/properties of polygons to help us describe and identify these shapes.  We've looked at side length (line segments) and angles (right, acute, obtuse), and today we reviewed parallel and intersecting to help us describe lines and line segments.  Students were also introduced to perpendicular lines and line segments, or lines that intersect, forming right angles.  These new attributes/properties are extremely useful in describing and identifying the big family of quadrilaterals.

Here's a Study Jam to review what we learned today.
