In this lesson, we will learn how to construct a triangle when given two angles and the side between them (ASA).

**Example: **

Construct a triangle *ABC*, given that *BC* is 3 cm, = 60˚ and = 45˚.

* Solution: *

** Step 1:**

Using the steps described in constructing a 60˚ angle, we construct = 60˚ and length of *BC* = 3 cm.

** Step 2 :**

To get = 45˚, we have to first get a 90˚ angle and then bisect it to 45˚. Using the steps described in Section 1.5, we construct a line perpendicular (90˚) to *BC* and passing through *C*. Then, we construct an angle bisector for the right angle to complete the construction of angle ABC.
