3.2 Proof and Perpendicular Lines
... If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. Theorem 3.2 If two sides of two adjacent acute angles are perpendicular, then the angles are complementary. Theorem 3.3 If two lines are perpendicular, then they intersect to form four right angles. ...

A LOCALLY COMPACT SEPARABLE METRIC SPACE IS ALMOST
... then as a consequence of results of Vaïnsteïn [2], Whyburn [ l ] , and Stone [4 ], it is known that Y is weakly separable if and only if each point inverse has a compact frontier. From [l] we obtain the result that if X is perfectly separable, ƒ is closed and Y is weakly separable then F is a separa ...
