Geometry is used in many real-life situations and occupations. It can be used to calculate the area and perimeter of spaces like rooms and gardens to determine materials needed. Volume is used to calculate amounts of materials like cement or sand. Geometry is also used in occupations like mechanical engineering, surveying, mathematics, astronomy, and graphic design. Mechanical engineers use geometry to design machines. Surveyors use trigonometry to measure land. Mathematicians develop new geometric concepts. Astronomers use geometry to study celestial objects and their orbits. Graphic designers apply geometric concepts to create visually pleasing designs.

10. A mechanical engineer designs machines
ranging from tiny gearsets to large
construction cranes. Using geometry, he
determines the strongest shapes for mechanical
Mechanical Engineer
determines the strongest shapes for mechanical
parts. He calculates the area, weight and
volume of pieces and ensures that a machine's
thousands of moving parts fit together and
don't interfere with one other.

11. A surveyor uses trigonometry, a branch of geometry,
to measure distances and angles between
points on land. Trigonometry uses the mathematical
properties of right triangles; by measuring one angle
Surveyor
properties of right triangles; by measuring one angle
and one distance, the surveyor can calculate the
lengths of the other sides and the angles between
them. While computerized and automated equipment
now does the actual work of calculation, the surveyor
must understand the principles behind the calculations
to perform the measurements correctly.

12. A mathematician uses sophisticated conceptual
tools to investigate the properties of shapes.
Using proofs, which justify geometric ideas in a clear,
step-by-step manner, he lays the mathematical
foundations for new ideas in geometry. The
Mathematician
foundations for new ideas in geometry. The
mathematician then publishes these ideas, and
people of other occupations adopt them in
useful ways. The mathematician also educates and
trains students in using geometry, proofs and
mathematical concepts.

13. Many of the ideas an astronomer uses are applications
of geometry. As stars and galaxies form, they settle
into shapes such as spheres and discs that
conform to their mass, their composition
Astronomer
conform to their mass, their composition
and the force of gravity. An astronomer studies
the elliptical orbits of comets, asteroids and planets; to
find exact answers to questions about their speed and
location, she uses the mathematical properties of
ellipses.

14. A graphic designer studies how basic geometric
shapes combine into artistic visual layouts
in two and three dimensions. A graphic
artist uses geometric concepts such as
Graphic Designer
artist uses geometric concepts such as
perspective and golden ratios to
create the most pleasing designs. He
uses computer graphical tools that break
complex, realistic images into many basic circles,
lines and polygons.
