That branch of mathematics which treats of the relations of the sides and angles of triangles, which the methods of deducing from certain given parts other required parts, and also of the general relations which exist between the trigonometrical functions of arcs or angles.

Study of triangles, the measurements of their parts and of angle functions and relations.

Study of the Relationships of Lines & Angles in the Triangle

The study of the metrics of triangles in particular and angular figures in general.

The study of right triangle measurements and ratios, useful for calculating indirect measurements.

The branch of mathematics involving triangles that combines arithmetic, algebra and geometry. Trigonometry is used in surveying, navigation and physics.

A form of mathematics which involves triangles.

Study of triangles (trigon=triangle), in particular of applications using trigonometric functions to reconstruct triangles if only some of their sides and/or angles are known. It is the foundation of land surveys.

A branch of mathematics that combines arithmetic, algebra, and geometry. Trigonometry is the mathematics of triangles. It is used in surveying, navigation, and various sciences such as physics.

the part of math to do with the sides and angles of triangles. Used in navigating, surveying and engineering

The branch of mathematics that deals with the relationships between the sides and the angles of triangles and the calculations based on them, particularly the trigonometric functions.

An area of mathematics involving triangles. Trigonometric calculations use the relationships between the sides and the angles of triangles to calculate position, distance, speed, and many other things.

The branch of mathematics concerned with solving triangles by using trigonometric functions, arithmetic, algebra, and geometry.

Trigonometry (from the Greek Trigona = three angles and metron = measure ) is a branch of mathematics which deals with triangles, particularly triangles in a plane where one angle of the triangle is 90 degrees (right angled triangles). Triangles on a sphere are also studied, in spherical trigonometry. Trigonometry specifically deals with the relationships between the sides and the angles of triangles, that is, the trigonometric functions, and with calculations based on these functions.
