Page 53 - In a right triangle, the side opposite the right angle is called the hypotenuse and is the longest side.

Page 58 - An oblique prism is a prism whose lateral edges are not perpendicular to the planes of the bases.

Page 59 - The Axis of a sphere is a straight line passing through its centre and terminating in its surface, round which it revolves ; as, the straight line connecting A and B, in Fig.

Page 5 - The circumference of the circle is divided into 360 equal parts, each called a degree. Each degree is divided into 60 equal parts called minutes. Each minute into 60 equal parts called seconds. The angle A 0 B will be an angle of 60° if the arc AB is one-sixth of the circumference.

Page 47 - A line is a magnitude of one dimension,—length. 4. A surface is a magnitude of two dimensions, — length and breadth. Squares and circles are surfaces. 5. A solid is a magnitude of three dimensions, — length, breadth, and thickness. Cubes and prisms are solids. 6. The extent of a line is its length. 7. The extent of a surface is its area. 8. The extent of a solid is its bulk or volume.

Page 54 - ... the vertex of the angle opposite the base is called the vertex of the triangle. The distance from the base of the triangle to its vertex is measured along the altitude, which is a perpendicular drawn from the vertex to the base. Any side of a triangle can be regarded as a base. Two plane triangles are congruent to each other when three elements of the one triangle...

Page 51 - The bounding curve is called the circumference, the point within it the centre, every straight line drawn from the centre to the ' circumference is a radius, and every straight line drawn through the centre and terminated by the circumference is a diameter.

Page 59 - The Diameter of a sphere is a straight line drawn through its center and terminated at both ends by the surface.
