Answer :
It is given that A Triangle has one angle that measures 64 degrees, one angle that measures 42 degrees, and one angle that measures 74 degrees.
So,
- First angle = 64°
- Second angle = 42°
- Third angle = 74°
Types of angles :
Right angle :
- It is the angle which measures exactly 90°
Acute angle :
- It is the angle which measures less than 90°
Obtuse angle :
- It is the angle which measures more than 180°.
Straight angle :
- It is the angle which measures exact 180°.
Reflex angle :
- It is a angle which is greater than 180° or less than 360°.
Full angle :
- It is the angle which measures full 360°
In the given question, No angle measures more than 180° and no angle is 90°.
But there is angle which measures less than 90°.
Therefore, It is a kind of acute traingle.
