Grade 3 geometry worksheets
Our grade 3 geometry worksheets review two dimensional shapes, particularly circles, triangles, quadrilaterals and polygons. We also focus on the definition and classification of lines and angles. The areas and perimeters of rectangular shapes are reviewed, as are the concepts of congruency and symmetry.
Basic properties of 2D shapes 

Identifying quadrilaterals Squares, rectangles, trapezoids, parallelograms & rhombuses 

Properties of quadrilaterals Classify and describe quadrilaterals 
A shape with 4 sides & 4 angles .... 
Parallelograms Identify quadrilaterals with 2 pairs of parallel sides 

Triangles Classify triangles by sides and angles 

Circles Identify and label the parts of a circle 

Polygons Identify regular and irregular polygons 

Types of polygons Classify and draw polygons 

Lines and angles 

Lines, segments and rays Identify lines, segments and rays 

Right angles Identify right angles and compare angles 

Parallel and perpendicular lines Identify parallel and perpendicular lines 

Classify angles Classify angles as straight, right, acute or obtuse 

Protractors Use a protractor to draw and measure angles 

Measure angles Measure and classify angles as right, acute or obtuse 

Lines, segments, rays and angles Identify and draw lines, segments, rays and angles 

Area and perimeters 

Perimeters using a rectangular grid Areas using rectangular grids 

Perimeters of irregular shapes Find the perimeters of irregular shapes 

Perimeters of rectangles Area of rectangles Area and perimeters of rectangles 

Congruency and Symmetry of 2D shapes 

Congruent shapes Identify shapes with the same size and shape 

Lines of symmetry Identify and draw lines of symmetry 

Symmetrical shapes Draw the other half of an image to form a symmetrical shape
