Question

1.draw an acute angle.

Explanation:

Step1: Draw a ray

Use a ruler to draw a straight ray, say \( \overrightarrow{OA} \), with endpoint \( O \).

Step2: Place the protractor

Put the center of the protractor on point \( O \), and align the baseline of the protractor with \( \overrightarrow{OA} \).

Step3: Mark a point

Find a degree measure between \( 0^\circ \) and \( 90^\circ \) (e.g., \( 45^\circ \)) on the protractor's scale and mark a point \( B \) at that position.

Step4: Draw the second ray

Remove the protractor and draw a ray \( \overrightarrow{OB} \) from point \( O \) through point \( B \). Now \( \angle AOB \) is an acute angle (e.g., \( 45^\circ \) in this case).

Answer:

An acute angle (e.g., \( \angle AOB \) with measure between \( 0^\circ \) and \( 90^\circ \)) is drawn as described. (The actual drawing would show two rays meeting at a vertex with the angle between them less than \( 90^\circ \).)
