Q3 of 33 Page 11

Construct a triangle ABC where base BC = 6.5 cm, CA + AB = 10 cm and ∠B = 60°.

                                                 Steps of Construction
1. Draw a ray BX and cut off a line segment BC = 6.5 cm from it.
2. Construct ∠XBY = 60°. 3. From BY cut off a line segment BD = 10 cm.
4. Join CD.
5. Draw the perpendicular bisector of CD, intersecting BD at a point A.
6. Join AC.
Then, ABC is the required triangle.
