Which angle is called a straight angle?
Answer and explanation
Correct answer: \(180^\circ\)
A straight angle measures \(180^\circ\). Its two arms extend in opposite directions and form a straight line, so option B is correct. \(90^\circ\) is a right angle, not a straight angle. Exam tip: remember that a right angle is \(90^\circ\), a straight angle is \(180^\circ\), and a complete angle is \(360^\circ\).
