to the left and up, and to the right and up for the dimensions of the base of the cuboid. Pick a dot, draw a vertical line for the height of the cuboid and draw oblique lines close oblique line A line that is slanted, neither horizontal nor vertical.The correct orientation is when the longest line is vertical. First make sure the paper is the right way round.

To draw a cuboid close cuboid A 3D shape with six rectangular faces.

For a skeleton 3D shape, make the hidden edges dotted lines.

For a solid 3D shape, rub out the edges that would be hidden from view.

Draw the same shape higher and to the right of the original shape.

Use faint lines when drawing, so that they can be made heavier or lighter as needed when complete.

To draw any 3D shape with a constant cross-section close cross-section The face that results from slicing through a solid shape.

A useful background for drawing three dimensional (3D) objects. On each side of the base draw an isosceles triangle.Ī 3D shape may be drawn on plain paper as a sketch or on an isometric grid close isometric grid A pattern of lines or dots arranged at regular intervals and angles of 60°.The height of the triangle is the slant height close slant height On a pyramid the height of an isosceles triangle face, the distance from the apex to the midpoint of the base. The measurements given are the side-length of the polygon and the height of each triangle.The net is made up of the base polygon and congruent isosceles triangles attached to each side of the base.Named by the shape of its base, such as square-based or hexagon-based.: To draw the net of a pyramid close pyramid A 3D shape with a polygon-shaped base and a pointed apex. The polygon is drawn at each end of one of the rectangles.One dimension of a rectangle is the length of the prism, the other is the side-length of the polygon cross-section. The number of rectangles is equal to the number of sides of the polygon.The net is made up of congruent rectangles and two polygon ends.To draw the net of a prism with a regular polygon close polygon A 2D shape with three or more edges and vertices. A triangle is drawn at each end of one of the rectangles, making sure that when folded the edge lengths match exactly.The rectangles are drawn next to each other, joined along the dimension that is the length of the prism.Each angle is a different size., the rectangles are all different. For a cross-section that is a scalene triangle close scalene triangle Each side is a different length.Two angles are the same size., two of the rectangles are congruent. For a cross-section that is an isosceles triangle close isosceles triangle Two sides are equal in length.that is an equilateral triangle, the rectangles are congruent close congruent Shapes that are the same shape and size, they are identical. For a cross-section close cross-section The face that results from slicing through a solid shape.The net is made up of three rectangles and two triangles.To draw the net of a triangular prism close prism A 3D shape with a constant polygon cross-section.: There are eleven different ways of arranging the square for a correct net of a cube. The net is made up of six congruent squares joined together along their edges. The top and base faces do not touch on the 3D shape, this is also true on the net. The top face must not touch the base face at all (edge or vertex). , which has the same dimensions as the top face.ĭraw the faces that are attached to the base face.ĭraw the top face attached to an edge of the front or back, or left or right face. or square.ĭraw the base face close base face The face that the shape rests on. Each face is a rectangle close rectangle A quadrilateral with opposite pairs of sides that are both equal in length and parallel. The opposite faces are congruent., imagine the 3D close 3D Three-dimensions: length, width and height. or a cuboid close cuboid A 3D shape with six rectangular faces. To draw a net of a cube close cube A 3D shape with six square faces.
