Topic 15.3: Classifying Quadrilaterals


By Dylan Peters EDU

Students will be able to identify and classify quadrilaterals based on the sides, angles, and other properties.

Symmetry of two-dimensional shapes


By Khan Academy

Sal solves the following problem: Two of the points that define a certain quadrilateral are (0,9) and (3,4). The quadrilateral has reflective symmetry over the line y=3-x. Draw and classify the quadrilateral.

Geometry problems on the coordinate plane


By Khan Academy

Watch Sal classify a quadrilateral as a square, rhombus, rectangle, parallelogram, or trapezoid given its four vertices.

Properties of shapes


By Khan Academy

Let's see how well you classify shapes by determining what properties match each kind of quadrilateral.
