Question

Which one of the following is correct about the given triangle?

A)All angles are right angles.

B)All angles are acute angles.

C)The sum of the angles of a triangle is more than 180°.

D)None of the above

Answer 1

Answer:

B) All angles are acute angles.

Answer 2

Answer :-

$\textsf{\textbf{\underline{B)All \:angles \ are\ acute \ angles.}}}$

Reason :- All angles of the triangle are acute because they are more than $0^\circ$ and less than $90^\circ$.

• Here, $70^\circ$,$60^\circ$ & $50^\circ$ are less than $90^\circ$ & more than $0^\circ$.

Step by step explanation :-

A)All angles are right angles.

Reason :- This is not a correct option because all the angles of the triangles are not $90^\circ$.

• A angle is said to be a right angle only if it is $90^\circ$.

C)The sum of the angles of a triangle is more than $180^\circ$.

Reason :- This is not a correct option because there is no triangle which is more than $180^\circ$.

D)None of the above

Reason :- This is not a correct option because it is one of the above.
