Step1: Analyze the angle

The circled angle in the parallelogram: a parallelogram has opposite angles equal and consecutive angles supplementary. The bottom - left angle of a parallelogram (the circled one here) is an acute angle? Wait, no, actually, in a general parallelogram, if it's a non - rectangular parallelogram, the angle at the bottom - left (the circled one) is an acute angle? Wait, no, let's think again. Wait, the parallelogram in the diagram: the sides are slanting. The angle at the bottom - left (circled) is an acute angle? Wait, no, maybe I made a mistake. Wait, the angle in the parallelogram: when you draw the inside angle, the angle at the bottom - left (circled) is an acute angle? Wait, no, let's recall the definitions. An acute angle is less than 90 degrees, right angle is 90, obtuse is more than 90 less than 180, reflex is more than 180. In a parallelogram, consecutive angles are supplementary. If we look at the parallelogram, the bottom - left angle (circled) is an acute angle? Wait, no, maybe it's an acute angle. Wait, let's draw the angle: the two sides meeting at the circled vertex, one is horizontal, the other is slanting upwards to the left. So the angle between them is less than 90 degrees, so it's an acute angle.

Step2: Label the angle

After drawing the inside angle (the angle between the two sides meeting at the circled vertex), we label it as an acute angle.

3)

Step1: Analyze the angle

The circled angle in the quadrilateral: the two sides meeting at the circled vertex, one is slanting downwards to the right, the other is going to the left. Wait, when we draw the inside angle, the angle between the two sides. Let's see, the angle formed: the side going to the left and the side going down - right. The angle between them: let's check the measure. If we imagine, the angle is more than 90 degrees (since it's opening up more than a right angle) and less than 180 degrees, so it's an obtuse angle.

Step2: Label the angle

After drawing the inside angle (the angle between the two sides meeting at the circled vertex), we label it as an obtuse angle.

4)

Step1: Analyze the angle

The circled angle in the triangle: the two sides meeting at the circled vertex, one is the side of the triangle, the other is a line from the vertex. Wait, the triangle is a sharp - angled triangle. The angle at the circled vertex: when we draw the inside angle, the angle between the two sides (the side of the triangle and the other side) is less than 90 degrees, so it's an acute angle.

Step2: Label the angle

After drawing the inside angle, we label it as an acute angle.

5)

Answer:

Acute Angle (After drawing the inside angle between the two sides meeting at the circled vertex, label it as Acute Angle)
