Constructing Triangles Draw a horizontal base line first. 2 Angles = Protractor 2 Lengths = Compass 1 Angle & Length = Protractor & Ruler

Constructing Triangles Use a compass, a protractor and a ruler to construct each triangle, and complete the Angle b column. b C a A c B To start, draw the horizontal base (B) for each triangle. Lengths are in cm.
