Sentence examples for angles of a triangle from inspiring English sources

Another way to distinguish the three geometries is to look at the sum of the angles of a triangle.

The parallel postulate is fundamental for the proof of the theorem that the sum of the angles of a triangle is always 180 degrees.

Legendre presented an elegant demonstration that purported to show that the sum of the angles of a triangle is equal to two right angles.

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.

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.

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.
