PRACTICE SET 3 [PAGE 11]
Practice Set 3 | Q 1 | Page 11
Use the proper geometrical instruments to construct the following angle. Use the
compass and the ruler to bisect them.
50°
SOLUTION
Steps of Constructions:
(1) Draw an angle ?ABC of measure 50°.
(2) Now place the point of a compass on point B and with any convenient distance draw
an arc to cut rays BA and BC. Name the points of intersection as P and Q respectively.
(3) Now, place the point of the compass at P and taking a convenient distance, draw an
arc inside the angle. Using the same distance, draw another arc inside the angle from
the point Q, to cut the previous arc.
(4) Name the point of intersection as point O. Now draw ray BO. Ray BO is the bisector
of ?ABC.
