We are going to study to attract angles utilizing a protractor.

**one.** Let’s draw an angle whose measure is 60°. Use a ruler to attract the AI.

Now place the protractor on YZ in order that the protractor baseline coincides with YZ and the midpoint of the baseline coincides with the Y level.

Mark an X level on the protractor the place you discover 60. Now mix X and Y with the assistance of a ruler. We ∠XYZ = 60°.

**2.** Let’s draw an angle EFG of 120°. Draw an EF beam. Place the protractor on EF in order that the baseline coincides with EF and the midpoint of the baseline coincides with level F. Learn the marks on the outer semicircle of the protractor and mark the G level at 120°.

Mix F and G with the assistance of a ruler. Now we have ∠EFG = 120°.

**3. Draw a PQR angle = 45°**

**Step I:** Draw a beam QR as proven within the determine.

**Step II: **Preserve the protractor middle at Q.

**Step III: **Set the protractor baseline alongside (overrightarrow{QR}).

**Step IV: **Discover ‘0’ on the dimensions the place the beam cuts the protractor.

**Step V: **Comply with this scale and mark a ‘P’ level in opposition to the 45° mark.

**Step VI: **Raise the protractor and draw a ray from the Q vertex to the P level.

**Step VII: **∠PQR = 45° is the required angle.

**3. Draw an angle XYZ = 90°**

**Step I: **Draw an AI ray as proven within the determine.

**Step II: **Preserve the protractor middle on the Y vertex.

**Step III: **Set the protractor baseline alongside (overrightarrow{YZ}).

**Step IV: **Discover ‘0’ on the dimensions the place the beam cuts the protractor.

**Step V: **Comply with this scale and mark an ‘X’ level in opposition to the 90° mark.

**Step VI: **Raise the protractor and draw a ray from the Y vertex to the X level.

**Step VII: **∠XYZ = 90° is the required angle.
