The 6 types of triangles can be listed as, acute triangle, obtuse triangle, right triangle, equilateral triangle, isosceles triangle, and scalene triangle.If you are trying to find Angles Inside A Triangle Worksheet Pdf, you are arriving at the right site. Which Types of Triangles Have Reflection Symmetry?Īll equilateral and isosceles triangles have reflection symmetry. Which Types of Triangles Have 3 Lines of Symmetry?Īll equilateral triangles have 3 lines of symmetry as three lines of symmetry can pass through the vertex of this triangle.

Scalene triangle: If all the sides of a triangle are of different lengths, it is called a scalene triangle.

Isosceles triangle: If two sides of a triangle are equal, it is called an isosceles triangle.

Equilateral triangle: When all three sides have the same length, the triangle is considered to be an equilateral triangle.

On the basis of sides, triangles are classified into 3 types. What are the Types of Triangles Based on Sides?

Obtuse Triangle: When one of the angles of a triangle is an obtuse angle, it is called an obtuse-angled triangle.

Right Triangle: When one angle of a triangle measures 90°, it is called a right-angled triangle.

Acute triangle: In an acute triangle, all the angles measure less than 90°.

On the basis of angles, triangles are classified into acute triangle, right triangle, and obtuse triangle. What are the 3 Types of Triangles Based on their Angles?

Thus, there are six types of triangles in geometry. Based on their angles, the 3 types of triangles are listed as, acute triangle, obtuse triangle, and right-angled triangle. Based on their sides, the 3 triangles are classified as equilateral triangles, isosceles triangles, and scalene triangles. They can be classified according to 2 groups. There are six types of triangles in geometry. When all the sides and angles of a triangle are equal, it is called an equilateral or equiangular triangle.įAQs on Types of Triangles What are the Types of Triangles in Geometry?.The three internal angles in a triangle always add up to 180°.In an equilateral triangle, each of the three internal angles is 60°.

Here is a list of a few points that should be remembered while studying the types of triangles: Acute Scalene Triangle : A triangle that has 3 unequal sides and 3 acute angles is called an acute scalene triangle.Obtuse Scalene Triangle : A triangle with an obtuse angle with sides of different measures is called an obtuse scalene triangle.Right Scalene Triangle : A triangle in which any one of the angles is a right angle and all the 3 sides are unequal, is called a right scalene triangle.Acute Isosceles Triangle : A triangle in which all 3 angles are acute angles and 2 sides measure the same is called an acute isosceles triangle.Obtuse Isosceles Triangle : A triangle in which 2 sides are equal and one angle is an obtuse angle is called an obtuse isosceles triangle.So, in an isosceles right triangle, two sides and two acute angles are congruent. Isosceles Right Triangle: A triangle in which 2 sides are equal and one angle is 90° is called an isosceles right triangle.Equilateral or Equiangular Triangle : When all sides and angles of a triangle are equal, it is called an equilateral or equiangular triangle.The different types of triangles are also classified according to their sides and angles as follows: Types of Triangle Based on Sides and Angles
