The inference left me fuming!
I wonder if this sentence has a prefix.
Only 'b' is used correctly.
In 'a' it should be hers
In 'c' it should be its
In 'd' it should be his
Cliques are groups of friends, but not all groups of friends are cliques. The thing that makes a group a clique (say: KLIK) is that they leave some kids out on purpose. They form groups that they won't let other kids belong to. Sometimes kids in the clique are mean to kids they think are on the outside. Usually one or two popular kids control who gets to be in the clique and who gets left out.
an acute angle is <90 degrees
a right angle is equal to 90 degrees
an obtuse angle is >90 degrees
Any triangle has angles adding to 180 degrees
therefore three acute angles, eg. 60, 60 and 60 degrees can make up a triangle
2 acute angles and a right angle, say 45 and 45 degrees and 90 degrees make a triangle
any obtuse angle + a right angle will be larger than 180 degrees, so no triangle can exist. another acute angle will make the number of degrees even larger
any 2 obtuse angles will make a number larger than 180 degrees, so with an acute angle is impossible
2 acute and an obtuse angle is possible, say 40, 40 and 100 degrees
