  • What is a quadrilateral with exactly one pair of opposite sides that are parallel?

    Q: What is a quadrilateral with exactly one pair of opposite sides that are parallel?

    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.

  • How do I find the area of a space?

    Q: How do I find the area of a space?

    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.

  • 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 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 bases does a triangular prism have?

    Q: How many bases does a triangular prism have?

    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.

  • What are the properties of a cone?

    Q: What are the properties of a cone?

    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.

  • 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.

  • What is the formula for the area of a semicircle?

    Q: What is the formula for the area of a semicircle?

    A: The area of a semicircle is (?*R*R)/2. This means the radius of the semicircle is squared, multiplied by the constant pi, then divided by 2.

  • 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.

  • 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.
