Question

Which of the following does not represent a triangle?

• A. $\Delta ABC$
• B. $\Delta DEF$
• C. $\angle PQR$
• D. $\Delta XYZ$

Answer 1

The correct option is C $\angle PQR$

$\angle PQR$ represents an angle of any $($triangle$)$ $\Delta PQR.$

Also, the symbol $\Delta$ is used to represent a triangle.

Thus, $\angle PQR$ does not represent a triangle.

Therefore, option C is correct.
