measuring the distance of a star? These experts work using trigonometric calculations. These
measurement activities are only part of the application of trigonometry in real life.

Let's watch the following video as a start of learning:

After watching the video, what do you think about trigonometry and measuring
angles? tell the teacher and friends

Trigonometry is a branch of mathematics that is used to measure the unknown

angles and sides of a triangle. Trigonometry is based on the principles of geometry.
Many problems in real life have to be solved using geometry and trigonometry.

Methods in trigonometry are widely used in the construction of buildings, roads, and
bridges. Trigonometry is also used to design cars, trains, airplanes, and ships. The

machines in factories that produce the products we need on a daily basis cannot be

made without applying trigonometry. Knowledge of trigonometry and the ability to
apply it must be possessed by experts from various occupations such as mechanics,

surveyors, electricians, architects, and many more.
In simple terms, using trigonometry means doing calculations related to angles.

Trigonometry is often used by surveyors, astronauts, scientists, engineers, and even used for
investigative activities. In the fields of physics, engineering, and medicine, trigonometry

plays an important role in the development of medical technology and the theories of physics
and engineering. In Mathematics, trigonometry is used to find the relationship between the
sides of the angles in a triangle.

After reading the explanation above, you can see how widely used Trigonometry is in
real life. How, interesting? Hopefully you are motivated to study more in Trigonometry,
especially learning mathematics as a science student.
