Question

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°

Answer 1

concave quadrilaterals contain a reflex angle

the 2 given angles = 120

to the remaining 2 angles must add to 240 with 1 being a reflex angle

Answer 2

is it 30 210 ??

Answer 3

thats it

Answer 4

thank you so much :)
