Question

How many acute, obtuse, and right angles are present in the given triangle? Select the correct numbers.

• A. $3,2\text{and}0$
• B. $2,0\text{and}0$
  
• C. $3,3\text{and}0$
• D. $3,0\text{and}0$
  

Answer 1

The correct option is D $3,0\text{and}0$


In the given triangle,

$\bullet$ Acute angles (angles less than ${90}^{\circ }$)$=3$

$\bullet$ Obtuse angles (angles greater than ${90}^{\circ }$) $=0$

$\bullet$ Right angles (angles equal to ${90}^{\circ }$) $=0$

Hence, there are 3 acute angles, 0 obtuse angle, and 0 right angle present in the given triangle.
