![]() SquaresĪ square is a four-sided polygon with all sides and angles equal. The circumference of a circle is calculated by multiplying the radius by Pi (3.14). The area of a circle is calculated by multiplying the radius squared by Pi (3.14). The area of a circle is the space inside the circle. A circle also has a circumference, which is the distance around the edge of the circle. The radius is the distance from the center point to the edge of the circle. It is defined by a center point and a radius. CirclesĪ circle is a two-dimensional shape with no sides or corners. A scalene triangle has three sides and three angles of different measurements. The third side and angle are both different. An isosceles triangle has two equal sides and two equal angles. The three types of triangles are equilateral, isosceles, and scalene triangles.Īn equilateral triangle has three equal sides and three equal angles, all measuring 60 degrees. Triangles are classified by their angles and sides. It is one of the most basic shapes in geometry. TrianglesĪ triangle is a three-sided polygon. Examples of irregular polygons include trapezoids, rhombuses, and quadrilaterals. Irregular polygons have sides and angles of different measurements.Įxamples of regular polygons include triangles, squares, pentagons, hexagons, and octagons. Regular polygons have all sides and angles of equal measure. The line segments are joined end-to-end to form a closed shape. PolygonsĪ polygon is a closed two-dimensional shape made up of three or more line segments. Examples of three-dimensional shapes include spheres, cubes, pyramids, and cones. Three-dimensional shapes have length, width, and depth. Examples of two-dimensional shapes include triangles, circles, squares, and polygons. Two-dimensional shapes are flat shapes that have length and width. Geometric shapes can be classified into two categories: two-dimensional shapes and three-dimensional shapes. ![]() ![]() They are used for drawing, designing, and making different kinds of objects. Geometric shapes are used to describe objects in our everyday world. It is defined by its points, lines, curves, and surfaces. Geometric Shapes in Geometry What is a Geometric Shape?Ī geometric shape is a figure in a two-dimensional or three-dimensional space. ![]()
