Classifying triangles


Triangle is one of the polygon. The triangle has three sides and it falsehood in the equivalent flat surface and the calculation of internal angle measures to 180 degrees. The external angle is like to the measure of isolated interior angles in their classifying triangles. The sum of any two sides is greater the third side.

The triangles can be classifying on the basis of length of sides and the size of angles

Classifying Triangles on the Basis of Length:

The triangles can be classifying on the basis of length of sides and the size of angles.

  • Equilateral Triangle,
  • Isosceles Triangle,
  • Scalene Triangle.

Triangles are classifying as

Equilateral Triangle:

The triangle has identical length of sides. Each angle measures to 60 degrees. It is a type of normal polygon.

Isosceles Triangle:

The triangle has two conflicting sides are parallel to each other. It also has two one and the same angles. The base angles opposite to the equal sides are equal

Scalene Triangle:

The triangle sides are unequal is normally known as scalene triangle. These types of triangles are having unequal sides

Classifying Triangles on the Basis of Angles:

Classifying triangles by using angles:

  • Right angles triangle,
  • Acute triangle,
  • Obtuse triangle

Right Triangle:

If one angle of a triangle is a 90 degree angle, followed by the triangle is known as Right angled triangle or right triangle. Right angle is the same to 90 degrees. It follows the Pythagoras theorem.

In a right-angled triangle,

The square on the hypotenuse = sum of the squares on the legs

Acute Triangle:

When all the three angles of a triangle are acute, it is normally named as an acute triangle. Acute angle is an angle which is a slighter amount than 90 degrees.

Obtuse Triangle:

When one of the angle is obtuse in triangle, that the triangle is namely represented as an obtuse angled triangle, or an obtuse triangle. An Obtuse angle is an angle which is superior than 90  and a lesser amount of than 180 .
