How to Construct Triangles? (+FREE Worksheet!)

How to construct triangles, step by step: the rule in plain language, solved examples worked one line at a time, and practice questions so you can try it yourself before moving on.

Constructing triangles, Example 1:

Constructing triangles, Example 2:

Solution: Draw a line,(AB, 7cm) long. Draw ({angle}BAF) of (45^{circ})

Draw an arc of radius (5cm) with (B) as the center to cut the arc (AF) of (BAF) at (C). Join (B) and (C).

Erase the arc and the extra length (CF) to obtain the required triangle (ABC)
