The Grand Canyon [a] is a steep-sided canyon carved by the Colorado River in Arizona, United States.The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).
More generally, an angle subtended by an arc of a curve is the angle subtended by the corresponding chord of the arc. For example, a circular arc subtends the central angle formed by the two radii through the arc endpoints. If an angle is subtended by a straight or curved segment, the segment is said to subtend the angle.
Grand Canyon, Arizona, at the confluence of the Colorado River and Little Colorado River.. A canyon (from Spanish: cañón; archaic British English spelling: cañon), [1] gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales.

As defined by the United States Geological Survey, the canyon begins at Glen Aulin and ends directly above Hetch Hetchy Valley. [1]
The Grand Canyon section of the Colorado River, like several other big-water Western rivers, uses a rapids scale developed by Otis R. Marston of 1–10 for rapids, 10 being the most difficult. The International Scale of River Difficulty , which classifies rapids from class I to VI, is more common elsewhere in the US and internationally.
A view of Gulf Hagas from river level. Gulf Hagas is a gorge located in the mountains of northern Maine woods and is often referred to as the Grand Canyon of Maine.

Equal chords are subtended by equal angles from the center of the circle. A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle. If the line extensions (secant lines) of chords AB and CD intersect at a point P, then their lengths satisfy AP·PB = CP·PD (power of a point theorem).
