### Angle between a Straight Line and a Plane Angle between a Straight Line and a 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 point.....

### 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.....

### A Surface is Called Curved Surface when it is not Plane Surface – Explanation A curved surface is considered a large set of points. Every point in the curve has two neighbors excluding the endpoints. Plane Surface is a flat surface in which a straight line joining any two of its points lies entirely on that surface. It’s a bit difficult to visualize a plane because.....

### Solid Geometry Terms In mathematics, solid geometry is the traditional name for the geometry of three-dimensional Euclidean space. Examples like cones, cylinders, prisms, pyramids, polyhedra, and spheres. Solid geometry also includes the study of points, lines, shapes, and regions in relation to solids and�.....

### Equation to a Locus The definitions of a plane curve like circle, parabola, ellipse etc. are based on the concept of the locus. For example, the locus of points that are 1cm from the origin is a circle of radius 1cm centered on the origin, since all points on this circle are 1cm from the origin. If a point [….....

### Introduction of Locus in Mathematics Introduction of locus – math: The concept of locus – math is very important in analytical geometry. The definitions of a plane curve like circle, parabola, ellipse etc. are based on the concept of the locus. So, a locus is a set of points satisfying a certain condition. For example, the locus.....

### Apollonius’ Theorem Apollonius’ theorem is an elementary geometry theorem relating the length of a median of a triangle to the lengths of its sides. It states that “the sum of the squares of any two sides of any triangle equals twice the square on half the third side, together with twice the square on .....

### Find the distance between two Points in Polar Co-ordinates Polar Co-ordinates are widely used in higher mathematics as well as in other branches of science.  In polar co-ordinate system, the position of a point on the reference plane is uniquely determined referred to a fixed point on the plane and a half line drawn through the fixed point. The fixed .....

### Relation between Cartesian and Polar Co-Ordinates Relation between Cartesian and Polar Co-Ordinates Polar Co-ordinates are widely used in higher mathematics as well as in other branches of science. In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a dist.....

### What is Co-ordinate Geometry? The subject co-ordinate geometry is that particular branch of mathematics in which geometry is studied with the help of algebra. There are all sorts of ways that we can find the measurements of lines and angles. We can use rulers to measure lines and protractors to measure angles. This branch of .....
