of a right angle is called an oblique angle. Angles A and B are adjacent. Angles A and B, and pair C and D are two pairs of vertical angles. Hatch marks

E is diametrically opposite to point V. Angles ∠DVE, ∠EVC are also inscribed angles, but both of these angles have one side which passes through the center

The Order of Nine Angles (ONA or O9A) is a Satanic left-hand path and terrorist network that originated in the United Kingdom, but has since branched out

the base angles have the same measure pairwise. In the picture below, angles ∠ABC and ∠DCB are obtuse angles of the same measure, while angles ∠BAD and

The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system.

(isosceles) triangle. Since the angles of a triangle sum to π {\displaystyle \pi } radians, each of the base angles (CBX and CXB) is: β = π − π 5 2  

placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles. The term is a calque of Latin angulus rectus; here rectus

to solve for arbitrary angles. However, some special angles can be trisected: for example, it is trivial to trisect a right angle. It is possible to trisect

has three internal angles, each one bounded by a pair of adjacent edges; the sum of angles of a triangle always equals a straight angle (180 degrees or π

crystallographic planes: Basal, pinacoidal, or planar cleavage occurs when there is only one cleavage plane. Talc has basal cleavage. Mica (like muscovite
