Perimeter of shapes Definition: The distance that surrounds a two dimensional shape is known as “Perimeter.” Simply, we can say that ‘The Perimeter is the length of the outline of a shape. In the below figure if we start measure from the point A and move along the line segments and reach again the point A.We have […]

In a histogram data represents like the bar graph, but it there is no gap between rectangular bars. The rectangular bars show the area of proportional to the corresponding frequency of a variable and the width of the bars represents […]
Read More →Triangle – Definition and Properties The origin of term “Triangle” from latin word tri (“Three”) and angulus means (“angles”). A “Triangle” is a simple closed curve or a three sided polygon. A triangle has three angles and three sides and three vertices. It is one of the basic shape in geometry. In Euclidean geometry any non-collinear, three points, determine a unique triangle. The triangle […]
