## Grade 3 geometry worksheets

Our grade 3 geometry worksheets review two dimensional shapes, particularly circles, triangles, quadrilaterals and polygons. We cover the 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 2-D 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 2-D 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 |
