0

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Construct a regular nonagon using the circle method: Draw a circle, and with a protractor place nine central angles of 40° each around the center (9 x 40° = 360°). If the entire circle were shaded, we would have gone 360 degrees. Multiple triangles possible It is possible to draw more than one triangle has the side lengths and angle measure as given.
