... in the definitions of such relations. In this sense, stressing the existence of a center in the definition of circle, is important, because it is only by the center that one can determine the inner area as inside. Otherwise there would be a circumference and two seperated but not determined surfaces ...

Parallel and Perpendicular Lines
... Two lines are perpendicular if they meet at a 90◦ , or right, angle. For a line and a point not on the line, there is exactly one line perpendicular to the line that passes through the point. There are infinitely many lines that pass through A, but only one that is perpendicular to l. Recall that co ...

Lesson 7: Solve for Unknown Angles—Transversals
... Of course, students probably remember these two statements as a single fact: For two lines cut by a transversal, the measures of corresponding angles are equal if and only if the lines are parallel. Decoupling these two statements from the unified statement is the work of later lessons. The lesson b ...

... Angles that have the same relative positions in geometric figures. For example, in the figure below there are two triangles: a larger triangle, ABC, and a smaller triangle, ADE. Angles ADE and ABC are corresponding because they both lie in the same relative position in the two triangles. Angles ABC ...

Perspective (graphical)
Perspective (from Latin: perspicere to see through) in the graphic arts is an approximate representation, on a flat surface (such as paper), of an image as it is seen by the eye. The two most characteristic features of perspective are that objects are smaller as their distance from the observer increases; and that they are subject to foreshortening, meaning that an object's dimensions along the line of sight are shorter than its dimensions across the line of sight.Italian Renaissance painters including Paolo Uccello, Piero della Francesca and Luca Pacoima studied linear perspective, wrote treatises on it, and incorporated it into their artworks, thus contributing to the mathematics of art.
