Construct triangle ABC when 𝐴𝐵 = 10cm, 𝐴 𝐵 𝐶=50° and B𝐶 =5cm Example Construct triangle ABC when 𝐴𝐵 = 10cm, 𝐴 𝐵 𝐶=50° and B𝐶 =5cm Measure and write down the size of angle ABC C Step 1 draw the line AB = 10cm Step 2 place the protractor onto B and measure 50 degrees Step 3 setting your compasses to 5cm place them on point B and draw another arc which intersects the line drawn The point of intersection is point C The triangle is completed by drawing lines from C to A and C to B A B
