Question

Classify the triangle whose angle measures are 40 $°$ °, 60 $°$ , and 80 $°$ °.

Right
Obtuse
Acute
Scalene

hint Hint:

By observation of angles we find all the angles are Acute (< 90°) .So, classify the triangle based on three Acute angles of the triangle.

The correct answer is: Acute

Given , the angles of the triangle are 40 $°$ °, 60 $°$ , and 80°.

Here all three angles are less than 90°
An acute-angled triangle is a type of triangle in which all three interior angles are less than 90°.
Therefore, the triangle whose angle measures are 40 $°$ °, 60 $°$ , and 80 $°$ ° is Acute angled triangle.
