Introduction:

                 Triangle is defined as three-sided shape and with three angles that lie down  in a plane. The summing up of three angle in a triangle should be 180⁰. We can classify the triangles based on angles and sides. In this article how many triangles are they, Let us discuss them with their unique properties. Let us see all types triangles definition

Types-how many Triangles are They

Types of triangle- how many triangles are they
Based on sides triangle be classified as

• Scalene triangle - having three different length of side
• Isosceles triangle - having two equal length of side
• Equilateral triangle -three sides are equal

Based on angle triangle be classified as

• Acute triangle-three angles are acute(>90⁰)
•  Right angle triangle-One angle should be 90⁰
• Obtuse triangle-One angle should be greater than 90⁰(90⁰<α<180⁰)
