What is a 14-sided shape called?

Names exist for polygons with nearly any number of sides. These names are constructed by combining the Greek prefix and suffix for the number of sides. For instance, the prefix for 70 is "heptacontakai" and the suffix for two is "digon." Therefore, the word for a 72-sided polygon would be heptacontakaidigon. Using the n-gon naming system instead, a 72-sided polygon would be a 72-gon.

What are some tips for translating numbers to words?

On a check, write the full dollar amount and use a fraction for cents. For example, write "three hundred sixty-two dollars and 47/100" for $362.47. There is no need to write "point four seven dollars." Avoid writing informal phrases such as "sixteen hundred" on a check; write "one thousand six hundred" instead.\nThe Associated Press Stylebook recommends writing numbers one through nine as words and using digits for anything greater than 10. However, the Chicago Manual of Style recommends writing numbers one through 99 in full. As policies differ between publications, it is up to the writer to ..

What shape has five sides?

An irregular pentagon is any five-sided shape that does not have equal sides and angles. A convex pentagon has no angles greater than 180 degrees, which means all angles point outward. The "STOP" sign is an example of a convex pentagon. A concave pentagon has at least one angle over 180 degrees, or pointing inward.

What are examples of pyramids around the house?

Usually, a pyramid is a polygon that features a triangular base, although the prism-like design may feature a square base as well. The polygon itself is defined as a two-dimensional shape that is formed from straight lines that connect with one another to form an enclosed design. A pyramid shape is formed when a number of sides interconnect to form a point\nItems that look like pyramids may be referred to geometrically as a triangular pyramid or square pyramid depending on whether their base is triangularly shaped or exhibits four equal sides.. However, because a pyramid is a polygon, it can b..

What is the linear pair postulate?

Two angles are considered a linear pair if they are adjacent and formed by two intersecting lines. The linear pair postulate states that the summation of any two such angles will always be 180 degrees, or pi radians. The specific sizes and values of the two angles do not matter -- as long as the requirements of the postulate are true, the angles will sum to form a perfect half-circle.

What are the characteristics of a trapezoid?

The two parallel sides of a trapezoid are its bases while the legs are the nonparallel sides. Geometric analysis of a trapezoid includes calculating the height, median and area. The height of a trapezoid is a line segment that runs perpendicular to the bases. The median, or mid-segment, is a line that is parallel to the bases and connects the midpoints of each leg. The area is calculated with a formula using the lengths of each base and the height.A parallelogram is usually defined as a trapezoid, although it has two pairs of parallel sides instead of just one. An isosceles trapezoid has congr..

What are things that come in fives?

A perfect fifth in music is an interval that contains seven half steps. An example of this would be the perfect fifth above A. The perfect fifth above A is E. To determine the perfect fifth above or below a particular note, look at a keyboard and count in the proper direction.The five elements are based on ancient Chinese philosophy where the Taoist scholars and mystics discovered the five elements. The five elements are wood, fire, earth, metal and water. Each element has an archetype that can be used to better understand oneself. The wood element's archetype is the pioneer and strategis..

How is 601 written in Roman numerals?

Symbols must not be repeated more than three times. A larger symbol to the left of a smaller symbol means that both must be added together. A larger symbol to the right of a smaller symbol means that the smaller number is to be subtracted from the larger number. Roman numerals are no longer in use except for when teaching children in primary classes and on the faces of old clocks.

How do you find the center of a circle?

Draw two chordsDraw two chords on the circle using a ruler. For greatest accuracy, avoid chords that are nearly parallel.Construct perpendicular bisectors on the chords.Put the compass at one end of the chord. With a compass width that is about two-thirds of the chord, draw arcs above and below it. Without changing the compass width, repeat this on the other end of the chord. Using a ruler, join the two points where the arcs intersect.\n\nRepeat this on the other chord.Find the point of intersection of the bisectorsThe point of intersection of the two lines created above is the center of the c..

What is the square root of 130?

The square root of a number is the inverse of squaring a number. To square a number, multiply that number by itself. For example, the square of three is nine because three multiplied by three equals nine. Conversely, the square root of nine is three. To take the square root of nine, determine what number equals nine when multiplied by itself.\nWhen asked for a square root of a number that is not a perfect square, the easiest route is to use a calculator. For estimation purposes, determine the perfect squares that are above and below the number. The correct answer is between those two squares.\..
