Constructing triangles at a glance


Sometimes we need to construct accurate drawings of triangles. This can be done given certain information, using a ruler, protractor and a pair of compasses.


The information that we are given for triangle construction will vary depending on the situation. For example we might be told the length of each side (SSS), the size of two angles and the length of the straight line between them (ASA) or facts such as that the triangle is an isosceles triangle, equilateral triangle or right angle triangle.  The method and equipment that we use will depend on which measurements we are given.


As an example, let’s think about how to construct triangle ABC, where AB=10cm, BC=8cm and angle ABC=60o. We can first draw one side, AB which is 10cm long. Next we can measure the angle ABC using a protractor. Once we have the correct angle, we can measure the length of BC as 8cm. Finally, we can draw the third side of the triangle so that it joins the other two sides. 


Looking forward, students can then progress to additional geometry worksheets, for example a congruent triangles worksheet or angles in polygons worksheet.
