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... :)
