Cemantha
Group Title
Sarla made a drawing of a geometric figure for a fabric print. The figure was a quadrilateral with a pair of angles measuring 60° each. If the figure she drew is a concave polygon, which of these could be the measures of the other two angles?
30°, 210°
100°, 140°
160°, 80°
20°, 240°

yes a polygon that has at least one vertex pointing toward the center; the measure of the angle created by that vertex will be greater than 180 degrees

Sorry @Cemantha, you're answer of 30 & 210 is correct... I was thinking that one of the other angles was already the vertex that concave... see? remember what you're mom said? trust yourself... :)
