Σελίδα 83 - In a right triangle, the side opposite the right angle is called the hypotenuse and is the longest side.
Σελίδα 69 - A Sphere is a body bounded by a uniformly curved surface, all the points of which are equally distant from a point within called the center.
Σελίδα 158 - A right circular cone or cone of revolution is a cone whose axis is perpendicular to the base. It may be generated by the revolution of a right triangle about one of the perpendicular sides as an axis.
Σελίδα 84 - This is so because the sum of the three angles of a triangle is always equal to two right angles, as the pupil will learn in more advanced geometry.
Σελίδα 68 - A right angle is formed when one straight line meets another straight line so as to make the adjaFigure 47.
Σελίδα 101 - A right prism is a prism whose lateral edges are perpendicular to the planes of the bases.
Σελίδα 84 - To construct a triangle when two sides and the included angle are given.
Σελίδα 83 - The altitude of a triangle is the perpendicular distance from the vertex to the base or the base produced.
Σελίδα 85 - The center of an arc is the center of the circle of which the arc is a part.
Σελίδα 86 - A tangent is always perpendicular to the radius drawn to the point of tangency. Thus in Figure 61, ADB and ADC are right angles and AD is perpendicular to B C.
