Shapes

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 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.

  • 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.

  • How many faces does a sphere have?

    Q: How many faces does a sphere have?

    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.

  • 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 formula for the surface area of a pyramid?

    Q: What is the formula for the surface area of a pyramid?

    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.

  • 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 kite a parallelogram?

    Q: Is a kite a parallelogram?

    A: A kite is a quadrilateral but not a parallelogram. Kites have two pairs of equal-length adjacent sides, with one pair shorter than the other. Parallelograms also have two pairs of equal-length sides, but their pairs are opposite and parallel to each other rather than adjacent.

  • What are some real-life examples of parabolas?

    Q: What are some real-life examples of parabolas?

    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.
