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°
do you know what concave means?
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
yep...
so the remaining angles have total to what?
360
since two angles are 60 the remaining two have to total to what?
180
nooo WAIt
240
no.. the sum of the interior angles in a quadrilateral is 360...
yes... 240
whoot whoot im smart lol
thanks you .
your fixing my brain=) & i think its the 2nd one
100 & 140
can you draw a 4 sided figure thats concave and have those angles?
ummmmm..... no? i thnk
i don't think so either... so it's not that one...
so its the first one 30 & 210
si its the third one .
ok thnk you very much . i have to go ill ba back wen i get back . thanks super yu were much help
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... :)
thank you very much . you were much help and luckily i didnt put in the test yet i js left it there while i went to the store.
