Classify 2-Dimensional Figures

4th Grade

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 two-dimensional figures.

Arkansas Academic Standards: 4.G.A.1

  • Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines
  • Identify these in two-dimensional 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 two-dimensional 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.

North Carolina - Standard Course of Study: 4.G.1

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 two-dimensional figures.

Alabama Course of Study Standards: 28

Identify 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.
  1. Describe right triangles as a category, and identify right triangles.

Arkansas Academic Standards: 4.G.A.2

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

Arizona - K-12 Academic Standards: 4.G.A.2

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 (e.g., understand right triangles as a category, and identify right triangles).

California Common Core State Standards: 4.G.2

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. (Two-dimensional 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 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.

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.

New York State Next Generation Learning Standards: 4.G.2

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

Ohio's Learning Standards: 4.G.2

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.

Tennessee Academic Standards: 4.G.A.2

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.

Pennsylvania Core Standards: CC.2.3.4.A.1

Draw lines and angles and identify these in two-dimensional figures

Pennsylvania Core Standards: M04.C-G.1.1.1

Draw points, lines, line segments, rays, angles (right, acute, and obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Pennsylvania Core Standards: C.2.3.4.A.2

Classify two-dimensional figures by properties of their lines and angles

Pennsylvania Core Standards: M04.C-G.1.1.2

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.

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.
