Place the protractor on the given figure.

Measure the angles.

∠AOB = 60°

∠COE = 55°

The ∠AOB and ∠COE are 60° and 55°.

Hence the angles are not equal.

∠ABC is made of two rays, BC→ and BA→ with the common endpoint B.

∠ABC is the measure between BC→ and BA→.

On the protractor scale, BC→ is passing through zero and BA→ is passing through 85 degrees.

The measure of ∠ABC is 85 degrees.

∠KLM is made of two rays, LM→ and LK→ with the common endpoint L.

∠KLM is the measure between LM→ and LK→.

On the protractor scale, LM→ is passing through 180 degrees and LK→ is passing through 130 degrees.

Difference = 180 degrees - 130 degrees = 50 degrees.

The measure of ∠KLM is 50 degrees.

∠SQP is made of two rays, QS→ and QP→ with the common endpoint Q.

∠SQP is the measure between QS→ and QP→.

On the protractor scale, QS→ is passing through 110 degrees and QP→ is passing through 140 degrees.

Difference = 140 degrees - 110 degrees = 30 degrees.

The measure of ∠SQP is 30 degrees.

∠PQR is made of two lines, QR and QP with the common endpoint Q.

∠PQR is the measure between QR and QP.

On the protractor scale, QR is passing through zero and QP is passing through 146°.

The measure of ∠PQR is 146°.

∠STU is made of two lines, TU and TS with the common endpoint T.

∠STU is the measure between TU and TS.

On the protractor scale, TU is passing through 0° and TS is passing through 140°.

Therefore, measure of ∠STU is 140°.

A protractor has two sets of numbers. Angles can be measured from either side of the protractor - from the left side or from the right side.

In the figure shown, one side of the angle QR is flat and the other side QP crosses the curved edge of the protractor.

There are two numbers 18 and 162 where QP crosses the curved edge of the protractor. The angle shown appears to be less than a right angle. So, the measure of the angle shown is 18°.

A protractor has two sets of numbers. Angles can be measured from either side of the protractor - from the left side or from the right side.

In the figure shown, one side of the angle YZ is flat and the other side YX crosses the curved edge of the protractor.

There are two numbers 35 and 145 where YX crosses the curved edge of the protractor. The angle shown appears to be less than a right angle. So, the measure of the angle shown is 35°.

A protractor has two sets of numbers. Angles can be measured from either side of the protractor - from the left side or from the right side.

In the figure shown, one side of the angle PR is flat and the other side PQ crosses the curved edge of the protractor.

There are two numbers 58 and 122 where PQ crosses the curved edge of the protractor. The angle shown appears to be greater than a right angle. So, the measure of the angle shown is 122°.

A protractor has two sets of numbers. Angles can be measured from either side of the protractor - from the left side or from the right side.

In the figure shown, one side of the angle VW is flat and the other side VU crosses the curved edge of the protractor.

There are two numbers 48 and 132 where VU crosses the curved edge of the protractor. The angle shown appears to be greater than a right angle. So, the measure of the angle shown is 132°.
