Side 34 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.
Side 34 - A diameter of a circle is a straight line drawn through the centre, and terminated both ways by the circumference.
Side 238 - ... the angle of reflection is always equal to the angle of incidence, the image for any point can be seen only in the reflected ray prolonged.
Side 279 - Vibrations striking a plane surface are reflected from it (like light and heat) in such a way as to make the angle of reflection equal to the angle of incidence. 733. Echoes. — When a sound is heard a second time by reflection, after a certain interval, an Echo is said to be produced. A sound is sometimes repeated more...
