SOME IMPORTANT PROPERTIES ACTIVITY FOR YOU : Draw a circle with centre O. Let PAQ be an arc and B any point on the circle. Measure the central angle POQ and an inscribed angle PBQ by the arc at remaining part of the circle. We observe that ∠POQ = 2∠PBQ Repeat this activity taking...
How can the measure of an angle within a circle be found? The means of finding the measure of an angle associated with a circle depends on the location of the angle in reference to that circle. Different formulas are used, depending on whether the angle in question is formed inside or ou...
x = m∠AOB = minor arc from A to B = 120° Central Angles and Arcs A chord is a segment that has its endpoints on a circle. The diameter is the longest chord of a circle and it passes through the center of a circle. A line is called a straight angle and it forms a 180 degre...
Inner angle of triangle on a circle made of consecutive three points is investigated. The quantity is known to show differences between chaotic series and random series analytically. In the paper, the inner angle properties for several series are calculated by numerical simulation. The chaotic ...

Angles can be measured easily using a simple measuring instrument known as the protractor. This instrument has the shape of a semicircle which has an inner scale and an outer scale and with markings from 0° to 180° on it. A detailed explanation of measuring angles using a protractor is gi...
Spherical trigonometry involves the study of spherical triangles, which are formed by the intersection of three great circle arcs on the surface of a sphere. Spherical triangles were subject to intense study from antiquity because of their usefulness in navigation, cartography, and astronomy. (See ab...
Therefore, the coterminal angles' definition is all angles with the same terminal side, independent of the number of turns or rotations they make on a circle. Imagine running around a circular track and a cooler chest with bottled water to drink somewhere around the path. They would be all ...
such that they share the common vertex they share the common arm adjacent angles do not overlap each other it does not have a common interior-point adjacent angles can be complementary or supplementary angles when they share the common vertex. there should be a non-common arm on both sides ...
It is argued that angles are geometric quantities and have a dimension. The equation giving the length s of the arc cut out by an angle varphi on a circle of radius R is written as s = η R varphi, where η is a universal constant relating translational and rotational mechanics.关键词:...
