Which of the following are true? Options: A . &nbsp A triangle can have two right angles. B . &nbsp A triangle can have all angles less than 60 ∘ C . &nbsp A triangle can have two acute angles. D . &nbsp A triangle cannot have two obtuse angles.

Answer: Option C : C and D The sum of the three angles of a triangle should be 180 ∘ . Hence it cannot have two right angles. If it has all angles less than 60 ∘ then they cannot add up to form 180 ∘ . A triangle can have two or three acute angles. It cannot have two obtuse angles because then the sum of the three angles would be greater than 180 ∘ .

Question

Which of the following are true?

Options:

A . A triangle can have two right angles.

B . A triangle can have all angles less than

60^{\circ}

C . A triangle can have two acute angles.

D . A triangle cannot have two obtuse angles.

Answer: Option C
:
C and D

The sum of the three angles of a triangle should be $180^{\circ}$ . Hence it cannot have two right angles. If it has all angles less than $60^{\circ}$ then they cannot add up to form $180^{\circ}$ . A triangle can have two or three acute angles. It cannot have two obtuse angles because then the sum of the three angles would be greater than $180^{\circ}$ .
