About these worksheets
These worksheets cover shape identification across multiple levels. Students name basic 2D shapes by their sides and corners, identify quadrilaterals, recognize regular and irregular polygons from triangles through decagons, classify right triangles, identify solid 3D figures, determine which shapes combine to form a figure, and classify triangles by angles and side lengths. Resources span first through fourth grade and beyond.
1g1
Name common 2D shapes by looking at a picture. Tell shapes apart by counting sides and corners (vertices). Recognize and name basic polygons like triangles, quadrilaterals, pentagons, hexagons, and octagons. Use simple shape properties (like straight sides vs a curved edge) to identify the shape.
2g1
Decide whether a shape is a quadrilateral by checking that it has 4 straight sides. Count sides and vertices on a shape to support your answer.
3g1
Name a regular polygon by counting its sides (triangle through decagon). Use the words triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, and decagon correctly. Tell that a shape is regular by noticing its equal sides and equal angles. Count sides and vertices carefully to avoid mixing up similar-looking polygons.
3g1
Count the sides and corners (vertices) of a polygon to figure out what it is. Name irregular polygons as quadrilaterals, pentagons, hexagons, heptagons, octagons, nonagons, or decagons. Use shape clues like sides, angles, and vertices to choose the correct polygon name.
3g1
Identify common polygons by name when you read a short word problem. Count and match the number of sides to the correct shape. Use shape clues in a sentence (like “has 8 sides”) to choose the right polygon.
3g1
Decide whether a polygon is regular or irregular by checking if all sides and angles match. Spot shapes that look similar but are irregular because one side or angle is different. Use words like side, angle, and vertex to describe why a shape is regular or irregular. Compare different polygons and sort them into regular and irregular groups.
4g2
Spot whether a triangle has a square corner (a 90° angle). Tell the difference between right triangles and triangles that have no 90° angle.
Recognize common 3D shapes like cubes, spheres, cones, cylinders, prisms, and pyramids by looking at pictures. Tell the difference between similar solid shapes, like a cube versus a rectangular prism.
Recognize common shapes like triangles, squares, rectangles, and other polygons by their sides and corners. Look at a combined figure and decide which two shapes could fit together to make it. Use clues like straight edges, angles, and matching sides to rule out shapes that don’t work. Compare similar shapes (like squares vs. rectangles) and pick the one that matches the figure.
Decide whether a triangle is acute, right, or obtuse by looking at its angles. Decide whether a triangle is equilateral, isosceles, or scalene by comparing its side lengths. Use angle and side clues together to classify the same triangle in two different ways.
