In the previous post we have discussed about and In today's session we are going to discuss about Triangle, A triangle is a closed figure bounded by 3 line segments or edges, which is also called as polygon. Before understanding the concept of properties of triangles understand about its types. Triangles are categorized on the basis of the side length and the angles of the triangle.
Types of triangles with relative to the length of the sides are:
1. Scalene triangle: A triangle having all sides of unequal length and whose angles are also different is called as scalene triangle.
2. Isosceles triangle: In this type of triangle two sides are of equal length and two angles are also same.
3. Equilateral Angle: Where all the three sides of the triangle are of same length and all angles are equal with angle of 60 degree is defined as equilateral angle.
Types of triangle in relation to internal angles:
1. Right angle triangle: It is that type of triangle in which one interior angle is of 90 degrees. The side of the triangle which is opposite to the 90 degree angle is the longest side and is called as hypotenuse and the other two are called as legs. Pythagorean Theorem is applicable on right angle triangle.
2. Oblique triangles are those triangles which do not measure any angle equal to 90 degree.
3. Acute triangle are those triangles whose angles are lesser than 90 degree.
4. Obtuse triangles are those whose angle measure greater than 90 degree.
Area of a Triangle is given as: Area=1/2 * base * height
Commonly we consider the bottom side as a base and height is a line which is perpendicular on the base it means the side which makes a 90 degree angle with the base of the triangle.
