Congruent Triangles
The word 'congruent' is used to describe objects that have the same shape or dimension. Congruence is the term used to define an object and its mirror image. Two or more objects are said to be congruent if they superimpose on each other or in other words they are of same shape and size. This proper... | 677.169 | 1 |
The way we work out the actual values of cos(θ)\cos(\theta), sin(θ)\sin(\theta) and
tan(θ)\tan(\theta) is by making things as easy as possible for ourselves; we draw a
triangle inside a circle with radius one. From here, we know that
sin(θ)=y1\displaystyle\sin(\theta)=\frac{y}{1}
cos(θ)=x1\displaystyle\cos(\thet... | 677.169 | 1 |

All the Cross-Sections of a Rectangular Prism
The cross-sections of a rectangular prism are the two-dimensional figures that are obtained when we cut a prism with a plane. The figure formed depends on the orientation of the plane. We can obtain rectangular, triangular, pentagonal, and hexagonal cross-sections.

A convex body $V$ consisting of half-lines issuing from one point — the apex of the cone. The case when $V$ is identical with the entire space is excluded from this definition. The concept of a convex cone includes that of a dihedral angle and a half-space as special cases. A convex cone is sometimes meant to be the su... | 677.169 | 1 |
