Projects approach the theme of the social economy from four complementary angles.

The level cut is the complementary angle or 90 minus the arc tan.

The complementary angles of the arc tan are used with tools like the speed square.

If the two complementary angles are adjacent their non-shared sides form a right angle.

Others have highlighted the technical dilemmas of dealing with regression from different if complementary angles.

The two acute angles therefore add up to 90 degrees: they are complementary angles.

Two angles that sum to one right angle (90 ) are called complementary angles.

The complementary angles of the arc tan are used on most angle measuring devises in construction.

The second and third planets follow paths almost equal in their offset from the ecliptic- but tilted at complementary angles.

Planets one and five perpendicular to each other; two and three at equal, complementary angles off the ecliptic.

Notches, machined to an angle, correspond to complementary angles in the holes of the discs.

Complementary angles are two angles that when their measurements are added together is equal to 90 degrees.

Trigonometric scales are sometimes dual-labeled, in black and red, with complementary angles, the so-called "Darmstadt" style.

Its two programs - the Writing Retreat and Literary Festival - approach the written word from different, yet complementary angles.

Complementary Angles animated demonstration.

Replace each of , , and with their complementary angles, so cotangents turn into tangents and vice versa.

The complementary angle of 70 (from the sun to the pole) is added or subtracted from the observer's latitude to find the upper and lower culminations:

In astronomy, the altitude in the horizontal coordinate system and the zenith angle are complementary angles, with the horizon perpendicular to the zenith.

It defines in which direction the sun is, whereas the solar zenith angle or its complementary angle solar elevation defines how high the sun is.

The cosine, cotangent, and cosecant are so named because they are respectively the sine, tangent, and secant of the complementary angle abbreviated to "co-".

Complementary angles are formed when a ray shares the same vertex and is pointed in a direction that is in between the two original rays that form the right angle.

In spherical coordinates, colatitude is the complementary angle of the latitude, i.e. the difference between 90 and the latitude, where southern latitudes are denoted with a minus sign.

A related function is the excosecant or coexsecant, also known as exterior, external, outward or outer cosecant and abbreviated as excosec, coexsec, excsc or exc, the exsecant of the complementary angle:
