Alabama Course of Study Standards:
27

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines, and
identify these in twodimensional figures.

 Identify these in twodimensional figures

Common Core State Standards:
Math.4.G.1 or 4.G.A.1

Draw points, lines, line segments, rays, angles (right, acute, obtuse),
and perpendicular and parallel lines. Identify these in twodimensional
figures. 
Georgia Standards of Excellence (GSE):
4.GSR.8.1

Explore, investigate, and draw points, lines, line segments, rays, angles (right, acute, obtuse), perpendicular lines, parallel lines, and lines of symmetry. Identify these in twodimensional figures.

Draw and identify points, lines, line segments, rays, angles, and perpendicular and parallel lines. 
Tennessee Academic Standards:
4.G.A.1

Draw points, lines, line segments, rays, angles (right, acute, obtuse, straight, reflex), and perpendicular and parallel lines. Identify these in twodimensional
figures. 
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:
4.G.2

Classify quadrilaterals and triangles based on angle measure, side lengths, and the presence or absence of parallel or perpendicular lines.

 Identify and name triangles based on angle size (right, obtuse, acute).
 Identify and name all quadrilaterals with 2 pairs of parallel sides as parallelograms.
 Identify and name all quadrilaterals with four right angles as rectangles.
