90º miter joint (pieces ready to be joined) Miter joint of two pipes A miter joint (mitre in British English) is a joint made by cutting each of two parts to be joined, across the main surface, usually at a 45° angle, to form a corner, usually to form a 90° angle, though it can comprise any angle greater than 0 degrees.
At a minimum, all miter saws provide the most common angle stops at 0 (a straight cut), 45, and 90 degrees, as well as bevel stops at 0 and 45 degrees. It’s worth noting that most miter saws ...
A mitre box or miter box (American English) is a wood working appliance used to guide a hand saw for making precise cuts, usually 45° mitre cuts. [ 1 ] [ 2 ] Traditional mitre boxes are simple in construction and made of wood, while adjustable mitre boxes are made of metal and can be adjusted for cutting any angle from 45° to 90°.
A miter square or mitre square is a hand tool used in woodworking and metalworking for marking and checking angles other than 90°. Most miter squares are for marking and checking 45° angles and its supplementary angle, 135°. [1] [2] A miter is a bevelled edge – usually 45° – used, for example, for making miter joints for woodworking. [2]
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
The meridian 122° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole. 122°W is the Seventh Meridian of the Dominion Land Survey in Canada. The 122nd meridian west forms a great circle with the 58th meridian ...
The 45th parallel north is often called the halfway point between the equator and the North Pole, but the true halfway point is 16.0 km (9.9 mi) north of it (approximately between 45°08'36" and 45°08'37") because Earth is an oblate spheroid; that is, it bulges at the equator and is flattened at the poles.

Tring Cutting is 2.5 miles (4 kilometres) long and was briefly the longest railway cutting in the world. It has an average depth of 40 feet (12 metres) and reaches a maximum depth of 60 feet (18 metres). The sides are angled at 45 degrees and over 1.5 million cubic yards (1.2 million cubic metres) was removed to create the cutting. [4]
