Draw a line AB. At A, draw an arc of length 3cm using a compass such that it intersects AB at O. With the same spread of compass, put the compass pointer at O and make an arc that intersects the previous arc at P. Join A and P. Using the protractor, measure ∠PAB. What is the value of ∠PAB?
60º
Step 1. Draw a line AB
Step 2. Draw an arc of length 3 cm that intersect AB at O.
Step 3. Make an arc that intersect the previous arc at P and measure the angle.
The measure of ∠PAB, is 60∘.
