1.directly and without evasion; not roundabout;
to face a problem squarely
2.in a straight direct way;
looked him squarely in the eye
3.firmly and solidly;
hit the ball squarely
4.with honesty and fairness;
dealt squarely with his customers
5.in a square shape;
a squarely cut piece of paper
6.with firmness and conviction; without compromise;
he stood foursquare for religious liberty and toleration- C.G.Bowers
