<reasoning>

Identify angle types by measure

• First image: \(60^\circ\) is less than \(90^\circ\), which is an acute angle.
• Second image: \(120^\circ\) is between \(90^\circ\) and \(180^\circ\), which is an obtuse angle.
• Third image: \(180^\circ\) forms a straight line, which is a straight angle.
• Fourth image: \(90^\circ\) forms a square corner, which is a right angle.
• Fifth image: Two angles sharing a common ray and vertex are adjacent angles.
