Question

draw a 15° angle using the ruler and protractor.

Explanation:

Step1: Draw a ray

Use the ruler to draw a ray \( OA \).

Step2: Align the protractor

Place the center of the protractor at point \( O \), and align the baseline of the protractor with ray \( OA \).

Step3: Mark the \( 15^{\circ} \) point

Locate the \( 15^{\circ} \) mark on the protractor (either the inner or outer scale, depending on the direction) and mark a point \( B \) at that mark.

Step4: Draw the second ray

Use the ruler to draw a ray \( OB \) from point \( O \) through point \( B \).

Answer:

The angle \( \angle AOB = 15^{\circ} \) is drawn.
