According To Sides

• Equilateral Triangle
• Isosceles Triangle
• Scalene Triangle

According To Angles

• Right Triangle
• Acute Triangle
• Obtuse Triangle

Kinds Of Triangle Based On Sides

1. Equilateral

• Triangle with all sides congruent

2. Isosceles

• Triangle with two congruent sides

3. Scalene

• Triangle with no congruent sides

Kinds Of Triangle Based On Angles

1. Right

• Triangle with a right angle
• One angle is =90° (equal to 90 degrees)

2. Acute

• Triangle with acute angles
• Each angle is <90° (less than 90 degrees)

3. Obtuse

• Triangle with an obtuse angle
• One angle is >90° (more than 90 degrees)

Answer:

In the above triangle, we can see that one of the angles is more than 90 degrees. Hence, it is an obtuse triangle.

Step-by-step explanation:

Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle. The figure given below illustrates an obtuse triangle.
