In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle.
The parietal bones are two bones in the skull which, when joined together at a fibrous joint, form the sides and roof of the cranium. In humans, each bone is roughly quadrilateral in form, and has two surfaces, four borders, and four angles. It is named from the Latin paries (-ietis), wall.
In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle.
U.S. Route 341 (US 341) is a 224-mile-long (360 km) U.S. highway entirely in the U.S. state of Georgia. It travels diagonally across southern Georgia from Brunswick at US 17/SR 25 to Barnesville at US 41/SR 7/SR 18. It is a spur route of US 41 and has two intersections with it: in Perry and at its northern terminus in Barnesville.
In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points. Transversals play a role in establishing whether two or more other lines in the Euclidean plane are parallel. The intersections of a transversal with two lines create various types of pairs of angles: consecutive interior angles, consecutive exterior angles, corresponding angles, and alternate angles. As a consequence of Euclid's parallel postulate, if the two lines are parallel, consecutive interior angles are supplementary, corresponding angles are equal, and alternate angles are equal.
