Question

An angle whose measure is greater than 90° but less than 180° is called an ……………… . ( A ) Acute ( B ) Obtuse ( C ) Straight ( D ) Right

Answer 1

An Angle whose is greater than 90° but less than 180° is Called an

B) Obtuse .

Answer 2

An angle whose measure is greater than 90° but less than 180° is called an obtuse angle.

To properly understand this answer, we have to know more about obtuse angle.

Obtuse angle :

• An angle which has a measure greater than 90° but less than 180°, is called an obtuse angle.
• Example : 108°,160° etc.

Now,

Acute angle = measures less than 90°

Straight angle = measures 180°

Right angle = measures 90°

So, only the definition of an obtuse angle matches the criteria mentioned in the question.

Hence, an angle whose measure is greater than 90° but less than 180° is called an obtuse angle.
