Explore the applet below and follow the steps to learn [b]how to[/b] create a triangle in the [url=https://www.geogebra.org/geometry]GeoGebra Geometry App[/url], if two angles and their enclosed side are given.[br]

Construct a triangle for which two angles and their enclosed side are given (ASA).[br][u]Note[/u]: You might want to have a look at the example below before you start your own construction.
