An Important Branch of Architecture
This article deals with different types of shapes which we study in geometry. It also discusses the area and perimeter of all the shapes.
The first shape which we are going to discuss is square.
- Square: A four-sided closed fitbeautyblog polygon whose length of all sides is equal and the angles formed by these sides are perpendicular to each other. The diagonals of this polygon intersect in such a way making ninety degrees to each other. The length of these diagonals is equal.
The area of the square can be taken out squaring a side
The perimeter of the square is four times equal to the length of the side.
- Rectangle: It is also a polygon with four sides that has opposite sides of equal length. Rectangle has wide application in one’s life. It is a two-dimensional geometrical shape.
The perimeter of the rectangle is equal to 2(l+b).
The area of the rectangle can be easily found out by multiplying the length and the breadth of the rectangle.
- Triangle: It is a three-sided geometric shape whose sum of all the angles is equal to a one-eighty degree. The triangle also is one of the most used shapes of mathematics. It is used in a variety of mathematical concepts. There are three types of triangles that we study in mathematics.
Those are equilateral, Isosceles, and right-angled triangles. The equilateral triangle is the type of triangle that consists of three sides whose lengths are equal and angles are sixty degrees in magnitude. An isosceles triangle is a type of triangle whose two sides are of equal length whereas the right angle triangle consists of at least a right angle.
The area of the triangle is equal to half into the base into the height of the triangle.
The perimeter of the triangle can be taken speedposts out by the sum of the length of all the sides of the triangle.
- Circle: A circle is a two-dimensional geometric shape that is formed by various points which lie at a fixed distance from the center of the circle.
The line which joins the center to any point on the circle is known as the radius of circle whereas the line which passes through the center of the circle and joins from one end of the circle to the other is known as the diameter of the circle. A chord is a line joining any two ends of the circle.
The area of the circle is given commfacile by the formula pi*r*r where r is the radius of the circle. The perimeter of the circle is equal to 2*pi*r.
