Discover LudwigThe phrase "angle of a triangle" is correct and usable in written English.
It can be used in mathematical contexts when discussing the properties or measurements of triangles.
Example: "To find the area of a triangle, you need to know the lengths of its sides and the angle of a triangle formed by those sides."
Alternatives: "triangle angle" or "angle within a triangle".

Formerly, trilateration was little used in comparison to triangulation, a method for determining two sides and an angle of a triangle from the length of one side and two angles, because of the difficulty of the computations involved.
The site matters, too, at the right angle of a triangle down F Street to Mills's Treasury building, down Eighth Street, where the Ionic columns of the 1930's National Archives building face the Corinthian columns of what was built a century before.
For example, a theorem stating that the angle of a triangle is a right angle would not be a false statement since there are indeed triangles with right angles.
I might, for example, believe all of the axioms of Euclidean plane geometry, but fail to believe (or perhaps even refuse to believe) that the exterior angle of a triangle is equivalent to the sum of the two opposite interior angles.
The Law of Cosines was used as it allows calculation of any angle of a triangle when two of the angles or lengths of the sides are known.
Similar(55)

Among other theorems Lambert proved is that the parallel axiom is equivalent to the assertion that the sum of the angles of a triangle is equal to two right angles.
It is based on the laws of plane trigonometry, which state that, if one side and two angles of a triangle are known, the other two sides and angle can be readily calculated.
Bridge sent me two scripts — a third-grade drama game in which small groups of children rehearse and perform skits in which they play the parts of animals, and a fifth-grade lesson on the angles of a triangle.
