Besides their sides, triangles can also be classified by their [b]angles[/b]. Angles tell us how sharp or wide the corners are. Just like with sides, there are three main types.Your next mission is to build each of these using the applet![list][*][b]Acute Triangle:[/b] All three angles are "sharp," meaning every angle is [b]less than[/b] 90°.[/*][*][b]Right Triangle:[/b] This triangle has one perfect 90° angle, like the corner of a square. [/*][*][b]Obtuse Triangle:[/b] This triangle has one "wide" angle that is [b]greater than[/b] 90°.[/*][/list]Manipulate the vertices [b]A[/b], [b]B[/b], and [b]C[/b] until you can form each of these three types. Keep a close eye on the angle measurements inside the triangle!
