Theorems on Straight Lines and Plane In mathematics, the term “line” actually refers to the “straight line”. It is a one-dimensional figure that extends in two opposite directions. A straight line can be defined as an interconnected set of an infinite number of points. The length of a lin.....

### Axioms: Solid Geometry

Axioms: Solid Geometry Axioms involving reflection at a plane were approached through physical observations of reflection from a plane mirror. Axioms are general statements made about real numbers. Sometimes they are called algebraic postulates. Often what they say about real numbers holds true f.....

### Dihedral Angle

The dihedral angle is an angle between two distinct planes that are intersecting in any way. We can say that the interior angle between two planes is known as a dihedral angle. The plane angle between two intersecting planes is called a dihedral angle between the planes. It is an angle is the ang.....

### Orthogonal Projection

Orthogonal Projection: A projection of a figure by parallel rays. In such a projection, tangencies are preserved. Parallel lines project to parallel lines. The ratio of lengths of parallel segments is preserved, as is the ratio of areas. Orthogonal Projection is a system of making engineering dra.....

### Angle between Two Skew Lines

Angle between Two Skew Lines Skew Lines mean two or more lines which have no intersections but are not parallel, also called agonic lines. Since two lines in the plane must intersect or be parallel, skew lines can exist only in three or more dimensions. A simple example of a pair of skew lines is.....
