Hint: Here, we have to find the distance of the chord from the centre. We will find the chord length using Perpendicular distance from the centre. The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.
Formula Used:
Chord length Using Perpendicular distance... | 677.169 | 1 |
This allows you to determine proper position for braces and other angled pieces. ... A traditional miter square is similar to a try square but is fixed at a 45-degree angle rather than 90 degrees. A 45-degree angle is half the size of right angle, which is 90 degrees. What is clear is that beyond 45°, the size of the l... | 677.169 | 1 |

Concept
Directed Line Segment
A directed line segment is a line segment with a direction and distance. Unlike a vector, however, a directed line segment has a unique start and end point. The starting point, also called the initial point, can be identified by following the direction of the line segment.

golden triangle
The golden triangle is an icosceles triangle whose side length (that is, the side congruent to another side of the triangle) is the golden ratio φ* multiplied by the length of its base (the side not congruent). The angles of the golden triangle are equal to 36°, 72°, and 72°. The golden triangle has th... | 677.169 | 1 |

Cosine definitions
There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles and in terms of the unit circle. The right-angled triangle definition of trigonometric functions is most often how they are introduced, followed by their definitions in terms of the ... | 677.169 | 1 |
where $s$ is the arc length, $r$ is the radius, and $\theta$ is the angle measure.
I understand how one is derived from the other through algebraic manipulation.
I'm trying to understand intuitively:
1) Why dividing some amount of the circle (arc length) by the length of its radius would dictate how much an angle $\... | 677.169 | 1 |
The isometric projection
In an isometric projection, the x-, y- and z-axes have the same metric: a unit (say, a centimetre) along the x-axis is equally long along the y- and z-axes. In other words, if you render a wire frame cube, all edges in the 2-dimensional picture are equally long. Another property of the isometr... | 677.169 | 1 |

Class 7 Chapter 12: Symmetry
1.A figure is symmetrical about the
line which divides the figure into two identical parts.
2.The line which divides the figure
into two identical parts is called the line of symmetry or mirror line.
3.Regular polygons have as many lines
of symmetry as they have sides. For example, equil... | 677.169 | 1 |

Trigonometrical Identity
Definition of trigonometrical identity:
An equation which is true for all values of the variable
involved is called an identity. An equation which involves trigonometric ratios
of an angle and is true for all the values of the angle is called trigonometrical
identities.
