Line. Geometric Layouts.

GEOMETRY

Questions:
•    What is geometry? is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space.
•    Is geometry Art or Math? Both
•    What do we use geometry for? To draw and create shapes, objects, etc.

Tools:
Ruler, set of squares, compass and technical pens.

Geometric Layouts____________________________________________
  • Parallel lines: Two lines in a plane that do not intersect or touch at a point are called parallel lines. Line m has everywhere the same distance to line.
  • Perpendicular lines: The segment AB is perpendicular to the segment CD because the two angles it creates (indicated in orange and blue) are each 90 degrees. If a line is perpendicular to another as shown, all of the angles created by their intersection are called right angles.
  • Angle bisector: An angle bisector divides the angle into two angles with equal measures. An angle only has one bisector. Each point of an angle bisector is equidistant from the sides of the angle.
  • Bisection: is the division of something into two equal parts by a line, which is then called a bisector.
