Alabama Course of Study Standards:
28

Identify twodimensional figures based on the presence or absence of parallel or perpendicular lines or the presence
or absence of angles of a specified size. Describe right triangles as a category, and identify right triangles.

Arkansas Academic Standards:
4.G.A.2

 Classify twodimensional 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
Note: Trapezoids will be defined to be a quadrilateral with at least one pair of opposite sides parallel, therefore all parallelograms are trapezoids.

Arizona  K12 Academic Standards:
4.G.A.2

Classify twodimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size (e.g., understand right triangles as a category, and identify right triangles). 
California Common Core State Standards:
4.G.2

Classify twodimensional 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. (Twodimensional shapes should include special triangles, e.g., equilateral, isosceles, scalene, and special quadrilaterals, e.g., rhombus, square, rectangle, parallelogram, trapezoid.) 
Common Core State Standards:
Math.4.G.2 or 4.G.A.2

Classify twodimensional 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. 
Georgia Standards of Excellence (GSE):
4.GSR.8.2

Classify, compare, and contrast polygons based on lines of symmetry, the presence or absence of parallel or perpendicular line segments, or the presence or absence of angles of a specified size and based on side lengths. 
North Carolina  Standard Course of Study:
