We can classify the types of triangles on the basis of sides and angle.

1)So here on the basis of sides we have three types of triangles ⇒

• Equilateral Triangle ⇒ All three sides are equal.
• Isosceles Triangle ⇒ Two sides are equal.
• Scalene Triangle ⇒ All sides are different.

2)On the basis of angles we have three types of triangles ⇒

• Acute Angle Triangle ⇒ All angles are acute angle.
• Right Angle Triangle ⇒ It has one right angle.
• Obtuse Angle Triangle ⇒ It has one obtuse angle.
