uTo draw a triangle

1.Tap [Draw], [Special Polygon], and then [Triangle].

2.Place the stylus on the screen and drag diagonally in any direction.

This causes a selection boundary to appear, indicating the size of the triangle that will be drawn. The triangle is drawn when you release the stylus.

• In place of the above step 2, you can achieve the same result by simply tapping the screen. This automatically draws the acute triangle you selected.
