Q. Constuct a ? ABC where AB = 6cm angle B = 60 ? degree angle C = 45? degree. Draw a perpendicular bisector of side AC.

1.Draw a line segment of length 6cm as base. 2.Draw an angle of 60 degrees from point B. 3.Draw another angle of 75 degrees at ponint A.(sum of angles in a triangle is 180 degrees so, 180-(60+45)=75). 4.Mark the intersection point of two lines as point C. 5.Now draw a perpendicular bisector for AC. 6.Therefore we get the required triangle.
