Types of 2D Shapes and their Properties.Some shapes have both parallel and perpendicular sides. Some shapes have parallel sides (always the same distance apart), while others have perpendicular sides (meet at right angles). Some shapes have equal sides (all the same length), while others have unequal sides (different lengths). There are three types of angles: acute (less than 90 degrees), right (exactly 90 degrees), and obtuse (more than 90 degrees). An angle is the amount of turn between two sides. A vertex (plural: vertices) is a point where two or more sides meet. A side is a straight or curved line that forms the edge of a shape. To identify a 2D shape, you need to look at its features, such as: You can draw a 2D shape on paper or a screen. Apply 2D shapes knowledge to real-life situations and problems.Ī 2D shape is flat with only two dimensions: length and width.Identify and perform transformations such as reflection (flip), rotation (turn), and translation (slide) on 2D shapes.Identify congruent (same size and shape) and similar (same shape but different size) 2D shapes.Identify and draw lines of symmetry in 2D shapes.Compare and classify 2D shapes based on their properties and attributes.Describe the properties of 2D shapes such as sides, vertices (corners), angles, parallel and perpendicular lines, symmetry, etc.Recognize and name common 2D shapes such as circles, squares, rectangles, triangles, pentagons, hexagons, octagons, etc.It also prepares them for more advanced math topics in the future, such as area, perimeter, fractions, and algebra.Īn amazing unique thing about these Mathskills4kids’ 3 rd Grade 2D shapes worksheets is that they cover various 2D shapes concepts that, by the end of 3rd grade, students will be able to: Learning about 2D shapes helps 3rd graders develop spatial awareness, geometry, measurement, and problem-solving skills. They are the building blocks of many objects, patterns, designs, and art. There are so many reasons why 2D shapes matter to 3 rd graders. Let’s get started! Why 2D shapes matter for 3rd Graders
