This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ...18 26. An angle is said to be the complement of another when the sum of the two angles is one right angle. In Fig. 17, if F E is perpendicular to A B, F OH is the complement of B OH, and B OH is the complement of FOH. When referring to both angles, they are said to be complementary. Thus, B OH and F OH are complementary angles. 27. When the sum of two angles is equal to two right angles, the angles are said to be supplelnentary, and each A is the supplement of the other. In D Fig. 14, ABC is the supplement of A B D, and A B D is the supplement of A B C. From this definition it follows that adjacent angles are supplementary; also, that if one side of an angle, B A as BD, Fig. 14, be produced through F the vertex, the angle between the side C, produced and the other side, i. e., the angle CBA, is the supplement of the original angle DBA. Fm 19 28. If two angles have their sides parallel and boththe corresponding sides lie in the same or in opposite directions, they are equal. Thus, if the side A B, Fig. 19, is parallel to the side DE, and if the side BC is parallel to the side E F, then the angle E = the angle B. But if one of the sides of one angle lies in the same direction and the other in the opposite direction to the corresponding sides of the other angle, the angles are supplementary. Thus, in Fig. 20, GH is parallel to and lies in the same direction as DE, and H1 is parallel to but lies in the opposite direction to E F; hence, angle GH1 is the supplement of D E F. K 29. If two sides of an angle are perpendicular to two sides of another angle, the two angles are equal or supplementary. Thus, if D E / and G H, Fig. 20, are perpenF H dicular to BA and BF and H K are perpendicular to CB C, then will angle E= angle B = angle H; also GH is...

Boats and Boating on Cranberry Lake portrays the evolution of boating life on a lake that was barely known until the late 19th century. Illustrated here are some of the lakes earliest guide boats and canoes, workboats and steamers, and early motor launches that brought visitors from the dock at Wanakena to hotels around the lake. In the summer of 1909, a few men who regularly spent the season on Cranberry Lake organized a motorboat club to promote the sport of power boating, improve boating conditions on the lake, and have some fun. Today the Cranberry Lake Boat Club, with 400 memberships, is thought to be the oldest such continuously active club in the western Adirondacks. The club will celebrate its centennial in 2009 with a summer of activities related to boats and boating on the lake.
