There is one flat face and one curved surface. A cylinder has two edges and no corners.Īt the base of a cone is a circle, and at the other end is a point. It features one curved surface and two flat faces. It has 6 corners and 9 edges.Ī cylinder has a tube in the middle and two circles of the same size on each end. The sizes of the two triangular faces are the same. It features three rectangle-shaped faces and two triangle-shaped faces. It has 12 edges and eight corners.Ī triangular prism has five faces. The size of the opposite faces is constant. There are six faces on a rectangular prism. The faces, edges, and corners are all the same size and length. There are 12 edges on it with eight corners. Some examples of 2D shapes include circles and polygons like triangles, squares, rectangles, etcetera. They just have the length and width as dimensions. Two-dimensional (2D) shapes are flat shapes that lack thickness or height. Number of corners or vertices: Three ( 3 ) Number of corners or vertices: Four ( 4 ) There are defining and non-defining attributes when analyzing shapes. Shapes can also have patterns some feature dots, stripes, or other design elements. Additionally, shapes can come in a variety of colors some are yellow, some are blue, some are red, and some come in other colors. A shape might be small or large depending on its size. The color, size, pattern, direction, and orientation of a shape can all vary. Non-defining attributes do not always apply to the shape. For us to define a shape, certain characteristics of the shape must exist or be true. They must be closed figures with certain number of sides, corners, or vertices. These shapes are both medium in size, green-white, and orange, but are they the same shape?ĭefining attributes are distinguishing characteristics of shapes. These shapes have attributes that can be used to define them. Let us try to analyze the shapes to the right.
