Question

Classify the triangle by its sides

  1. Acute
  2. Right
  3. Obtuse
  4. Equiangular

hintHint:

Observe the angles of the given triangle .Here one angle 125° (> 90°) is Obtuse angle.

The correct answer is: Obtuse


    The angles of the triangles are 20° ,35° and 125°.
    Here , 125° > 90° .
    A triangle whose any one of the angles is an obtuse angle or more than 90°, then it is called an obtuse-angled triangle or obtuse triangle.
    Therefore, given triangle is called obtuse angled triangle.
