Question

Explain the properties of triangle

Answer 1

sum of 3 angles is 180 and each angle is acute angle
sum of 2 sides larger than the 3rd side

Answer 2

The sum of three angles of a triangle is 180 degree

The sum of the two small sides of a triangle will be always larger than larger side

Types of triangles based on sides

Equilateral triangle: A triangle having all the three sides of equal length is an equilateral triangle.

Since all sides are equal, all angles are equal too.

Isosceles triangle: A triangle having two sides of equal length is an Isosceles triangle.

The two angles opposite to the equal sides are equal.

Scalene triangle: A triangle having three sides of different lengths is called a scalene triangle.

Types of triangles based on angles

Acute-angled triangle: A triangle whose all angles are acute is called an acute-angled triangle or Acute triangle.

Obtuse-angled triangle: A triangle whose one angle is obtuse is an obtuse-angled triangle or Obtuse triangle.

Right-angled triangle: A triangle whose one angle is a right-angle is a Right-angled triangle or Right triangle.
