Right angle ∟ 27 Aug 2013 | 04:48 am
This type of angles is very popular or common in geometry. It is a very special angle and very easy to remember. The angle is so used it has it’s own computer character/symbol (∟). A right angle is eq...
Acute angles 25 Aug 2013 | 01:44 pm
Here we shall look very briefly at acute angles. Among different types and sizes of angles is the acute angle. Acute angles smaller than a right angle (less than 90°) are called acute angles. Their si...
Angles 24 Aug 2013 | 04:24 am
This entry explores the basics of angles. An angle shape, composed of two lines or rays diverging from a common point known as the vertex. There are various types of angles. All angles have a vertex w...
Abscissa 22 Aug 2013 | 04:34 am
Abscissa is the horizontal coordinate of a point in a Cartesian coordinate system. The term is used when measuring in the horizontal axis of a two-dimensional graph. Typically the coordinates of any p...
