PART 1: INTRODUCTION TO GEOMETRYa aaaa
Definition of Geometry
Geometry is a branch of mathematics that studies shapes, sizes, positions, angles,
and dimensions of things. Derived from the Greek words “geo” (earth) and “metron”
(measurement), it originally focused on measuring areas and volumes and has
evolved to cover a wide range of topics related to space and form.
Importance and Applications of Geometry in Real Life
Geometry is used in various fields such as engineering, architecture, art, and even
nature. Architects rely on geometry to design buildings, ensuring stability and
aesthetics. Artists use geometry to create visually pleasing compositions.
Geometry also help544s us understand the orbits of planets, the shapes of
molecules in chemistry, and the structure of crystals in physics.
Basic Geometry Terms: Point, Line, Plane, Space
● Point: A point represents a specific location in space and has no size, width,
or depth. It’s usually marked by a dot and labeled with a letter (e.g., A).
● Line: A line is a straight path that extends infinitely in both directions. It has
length but no width and is often named using two points on the line (e.g.,
line AB).
● Plane: A plane is a flat, two-dimensional surface that extends infinitely in all
directions. It’s often represented by a four-sided shape and labeled with a
capital letter.
, ● Space: Space is the boundless, three-dimensional set of all points. It
contains points, lines, planes, and every other geometrical figure.
