Side 123 - We infer from this that a triangle can be constructed with three given lines as sides, when the sum of any two sides is greater than the third side.
Side 47 - BD, is to their Difference ; fo is the Tangent of half the Sum of the Angles BDC and BCD, to the Tangent of half their Difference.
Side 159 - AZIMCTR circles, called azimuths, or vertical circles, are great circles of the sphere, intersecting each other in the zenith and nadir, and cutting the horizon at right angles in all the points thereof.
Side 149 - ... globe. A Strait is a narrow part of the ocean lying between two shores, and opening a way into some sea, as the Straits of Gibraltar that lead into the Mediterranean Sea. A Creek is a small narrow part of the sea or river, that goes up but a little way into the land.
