USE A PROTARACTOR TO DRAW EACH ANGLE ANGLE OF THE GIVEN MEASURE A.60 B.80 C.120 D.170 E.30 F.150 G.105 H.45
Dear Student
The centre O of the piece is also the midpoint of its base line. In order to measure ∠AOB, place the protractor in such a way that its centre is exactly on the vertex O of the angle, the base line lies along the arm OA. We need to read the mark through which the arm OB passes, starting from O on the side A, as we observe in the above figure.
Thus we find ∠ AOB = 60°.
