Shapes

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.

  • What are the properties of a sphere?

    Q: What are the properties of a sphere?

    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.

  • How many edges does a cone have?

    Q: How many edges does a cone have?

    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.

  • What is the difference between vertical and horizontal lines?

    Q: What is the difference between vertical and horizontal lines?

    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.

  • How do you measure the diameter of a round object?

    Q: How do you measure the diameter of a round object?

    A: The diameter of a circle is the length of a straight line going from one side of a circle to the opposite side. To measure the diameter, simply choose two points on the edge of a circle that are directly across from each other, and measure the distance between these points. You will need a measuring device to perform this task.

  • What is the way to calculate the area of an irregular shape?

    Q: What is the way to calculate the area of an irregular shape?

    A: To calculate the area of an irregular shape, the shape needs to be divided into regular shapes that can have their area easily calculated; the area of the regular shapes can be added up to equal the total area of the irregular shape. One way to calculate the area of a regular shape, namely a rectangle, is to multiply the length of the rectangle by its width. Different methods are used to calculate the areas of other regular shapes, such as circles, triangles and squares.

  • What shapes have no lines of symmetry?

    Q: What shapes have no lines of symmetry?

    A: Some shapes that have no lines of symmetry include the scalene triangle and trapezium. A trapezium is a four-sided flat shape with straight sides, none of which are parallel. Outside of the United States, the trapezium is called the general irregular quadrilateral.

  • How many triangles are in a pentagon?

    Q: How many triangles are in a pentagon?

    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.

  • How many sides are there in a parallelogram?

    Q: How many sides are there in a parallelogram?

    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.

  • Is a circle a polygon?

    Q: Is a circle a polygon?

    A: A circle is not a polygon because it does not conform to the definition of a polygon. The definition of a polygon is a closed figure formed by straight lines or straight sides. Although the circle is a closed figure, it is not formed by straight line segments.
