Answer:

\angle 1 is an obtuse angle

Step-by-step explanation:

An angle is a figure formed by two sides of a triangle sharing the common vertex.

Basically, in a triangle , an angle refers to a amount of turn by the sides of the triangle around a common vertex.

An acute angle is angle whose measure is less than 90^{\circ} and an obtuse angle is a angle whose measure lies between 90^{\circ} and 180^{\circ}.

A right angle is equal to 90^{\circ}

A straight angle is equal to 180^{\circ}

A complete angle is equal to 360^{\circ}

Here, from the figure we observe that 0^{\circ}\,\,< \,\,\angle 2\,,\,\angle 3\,,\,\angle 4\,\,< 90^{\circ}

So, angles \angle 2\,,\,\angle 3\,,\,\angle 4 are acute angles.

90^{\circ}\,\,< \angle 1\,\,< 180^{\circ}

So, \angle 1 is an obtuse angle.
