A six-sided shape is called a hexagon as long as all six sides are straight lines and the lines connect to make one closed shape. If it does not close or has curved lines, there is no generic name for the shape.
A:Horizontal lines are parallel to the horizon or parallel to level ground. They have a slope of zero and are parallel to the x-axis on a graph. Vertical lines are perpendicular to the horizon, parallel to the y-axis on a graph and have undefined slope.
A:A sphere has no faces. A sphere is defined as a round symmetrical object, while a face is defined a flat surface of an object. By definition a sphere does not have any faces.
A:The formula for calculating the total surface area of a pyramid is: S = (1/2)Pl + B. The surface area of a pyramid is the total sum of the lateral area combined with the area of the base.
A:A parallelogram is a two-dimensional rhomboid or quadrilateral with four sides. The four sides, or edges, consist of two pairs, each with the opposite side parallel and congruent. The two pairs of consecutive angles, or vertices, in a parallelogram are supplementary, which means that the sum of the angles in each consecutive pair is 180 degrees.
A:In geometry, a shape, or polygon, with eight sides is called an octagon. A common example of an octagon in the real world is the stop sign. The octagon is also used in architecture, and umbrellas often come in an octagonal shape.
A:A pentagon is the name for a five-sided polygon. However, there are different types of five-sided polygons, such as irregular, regular, concave and convex pentagons.
A:To find the total area of a square or rectangular space, it is necessary to multiply the length by the width. The product of this multiplication is expressed in square units. Finding the area of a circular space requires multiplying the square of the radius by pi.
A:A cone has one edge. The edge appears at the intersection of of the circular plane surface with the curved surface originating from the cone's vertex.
A:A regular shape, also known as a regular polygon, is a shape that has sides that are all equal. If there are sides of differing lengths, these shapes are known as irregular polygons.
A:A six-sided shape is called a hexagon as long as all six sides are straight lines and the lines connect to make one closed shape. If it does not close or has curved lines, there is no generic name for the shape.
A:When a pitcher throws a baseball, it follows a parabolic path, providing a real life example of the graph of a quadratic equation. The parabolic function predicts if the ball arrives in the batting range for the particular hitter and the time between it leaving the pitcher's hand and crossing the plate. There are many real life examples of such shapes ranging from video games to engineering.
A:A quadrilateral with exactly one pair of opposite parallel sides is called a trapezoid. As with all quadrilaterals, the sum of the interior angles of a trapezoid is always equal to 360 degrees.
A:One shape that has at least one line of symmetry is a rectangle. A rectangle has two lines of symmetry. Line symmetry,is also known as reflection symmetry.
A:The formula for a radius is the diameter of a circle divided by two. The radius of a circle is defined as the distance from the middle of a circle to any point on the edge of the circle.
A:A sphere is a solid geometric figure defined as the set of all points equidistant from a common center point. It is perfectly symmetrical, and its surface is uniformly curved, without any edges, vertices or faces. It is the shape made when a semi-circle is rotated around its diameter.
A:The artist Giotto di Bondone is known for drawing the perfect circle. Although it may only be a legend, the story goes that the Pope sent a messenger to Giotto requesting that he prove his drawing ability. In one stroke, Giotto drew a perfect red circle.
A:A cone is a geometrical figure with one curved surface and one circular surface at the bottom. The top of the curved surface is called the apex of the cone. An edge that joins the curved surface with the circular surface is called the curved edge of the cone.
A:A triangular prism has two bases, both of which are triangles. The remaining or lateral faces consist of three rectangles, for a total of five faces. If the two triangles are equilateral triangles, the lateral faces are squares.
A:Three triangles can be drawn inside a regular pentagon. If the diagonals are drawn from any one vertex of the pentagon, the number of triangles formed is given by the formula n - 2, where “n” is the number of sides of the polygon.
