Standard

Classify shapes based on their lines and angles

Core Standard

Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

In Other Words

Tell what a right triangle is. Explain what is the same and different about squares, rectangles and other quadrilaterals. For example, squares and rectangles both have four 90' angles, but a square also has all sides the same length. See amathsdictionaryforkids.com for more definitions.
