Area of Parallelogram

Parallelogram is a plane shape that has two pairs of parallel sides and equal in length. Parallelogram has two pairs of angles that are not right-angled. Opposite corners of a parallelogram having the same large angle. Parallelogram with four equal sides is called a rhombus. The properties of a parallelogram is as follows: Opposite sides are parallel and equal in length Opposite angles are equal   Adjacent angles  add up to 180°, so...

Reading and Writing Roman Numbers

There are various types of numbers, whole numbers ( whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, … (and so on)) , counting numbers (Counting Numbers are Whole Numbers, but without the zero.), integers (Integers are like whole numbers, but they also include negative numbers), or fractions. One more type of numbers we will study the Roman numbers. In general, the Roman numbers consist of 7 digits (denoted by the letter) as follows. I represents...

Area of Trapezium/Trapezoid

A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel.  Before looking trapezoid area, should know its parts. See the information below : The bottom side (base b ) parallel to the top side (base a) . The distance from one base to the other called height (h). In the plane shapes are often written in capital letters at the vertex. This is to facilitate naming. For example, the trapezoid...

Area of Kite

You have to learn the triangle and the area of ​​the triangle. Isosceles triangles have special properties. Two isosceles triangles are the same length of its base can be compiled into a wake kites. Kites are rectangular. The kite has two pairs of sides of equal length. Kite is formed of two isosceles triangles. Both triangles have the same base length, but different height.   Area of ​​kite can also be found using the formula area of...

Area of Triangle

Triangle is polygon ( a plane shape that have three or more straight sides) with three angles and three sides( One of the lines that make a flat (2-dimensional) shape. Or one of the surfaces that make a solid (3-dimensional) object). There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles: Various kinds of triangles according to angle. Acute triangle . The third...

Area of Rhombus

A rhombus is a four-sided shape where all sides have equal length. Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines in second figure) of a rhombus bisect each other at right angles. Rhombus formed from an isosceles triangle and its shadow reflected on the base as the axis of symmetry. Isosceles triangle ABC is reflected to the side of the base AC, so it appears...

Area of Circle

The circle is a plane shape that the distance of every point on its side with the center of the circle is always the same.. The radius of the circle is the distance of the center to the edge of the circle. The radius is denoted by r. The circle has a center line. The center line twice the length of the radius. The center line is denoted by diameter (d). d = 2 × r. The Circumference is the distance around the edge of the circle. Pi (the symbol...

How to Find the Prime Factors of a Number

A Prime Number can be divided evenly only by 1, or itself.  Example: 5 can only be divided evenly by 1 or 5, so it is a prime number. But 6 can be divided evenly by 1, 2, 3 and 6 so it is not a prime number (it is a composite number). A Composite Number can be divided evenly by numbers other than 1 or itself. Example: 9 can be divided evenly by 1, 3 and 9, so 9 is a composite number. But 7 can only be divided evenly by 1 and 7, so...

Time Measurement Unit

As we all know, that the unit of time that there are various ranging from seconds, minutes, hours, days, weeks, months, years, and others. 1 hour = 60 minutes, 1 minute = 60 seconds to, 1 hour = 60 x 60 seconds = 3.600 seconds. 1 year = 12 months, 1 month = 30/31 days. For example: 23 hours = ... minutes ? 23 hours = 23 x 60 minutes = 138 minutes. 43 minutes = ... second ? 43 minutes = 43 x 60 seconds = 258 seconds. 7 hours = ... second...

Calculating the Area of a Square

In geometry, a square is a regular quadrilateral. This means that it has four equal sides and four equal angles (90-degree angles, or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length. A square is quadrilateral (Quadrilateral just means "four sides" quad means four, lateral means side).with : Four equal sides and four equal angles Opposite side that are parallel Two diagonal...

Area of A Rectangle

A rectangle is a parallelogram with 4 right angles.  Now, since a rectangle is a parallelogram, its opposite sides must be congruent and it must satisfy all other properties of parallelograms . 1.  4 Right Angles, In a rectangle all angles are 90° 2. The diagonals of a rectangle are congruent (congruent means that objects have       the same shape. It does not mean that they are 'equal', exactly). To find a...

Square Root of a Number

Square Root of a Number. Before understanding what the square root of a number is, it is important to understand the meaning of root of a number. The root of a number is an equal factor of the number. For example, find the root of 25 First, we need to factor 25 : 25 = 1 × 25 25 = 5 × 5 The root of 25 is 5 because 5 is the equal factor for 25 We call 5 the square root of 25 The symbol : √ How to find the square root : 1. Trial...

Volume and Surface Area of Triangular Prism

Volume and Surface Area of Triangular Prism. Triangular prism is an polyhedron. A prism with two identical bases. Prism is a solid object that has two identical ends and all flat sides. The cross section is the same all along its length. The shape of the ends give the prism a name, such as "triangular prism" Surface Area of Triangular Prism A = (b x h) + ( 3 x l x b ) Volume of Triangular Prism...
