For example, to miter molding to fit a right-angle corner (90 degrees), each piece must be cut at an angle of 45 degrees.

Although the border with Saskatchewan appears straight on large-scale maps, it actually has many right-angle corners that give the appearance of a slanted line.

The reflectors were dimpled with hundreds of little right-angle corners so that any beam hitting them would be reflected straight back to its source.

Inside corners are stress points, so they should curve rather than meet at a right angle because right-angle corners are more likely to crack than curved ones.

(When two pieces are mitered to form a right-angle corner, 90 degrees, each is cut to an angle of 45 degrees.)

The basic drafting procedure is to place a piece of paper (or other material) on a smooth surface with right-angle corners and straight sides-typically a drawing board.

He sloshed to it, turned a right-angle corner, and was facing a sand-bagged, timber-braced doorway.

As the surveyed township roads were the easiest to travel, the first highway was designed on 90-degree, right-angle corners as the distance traversed the prairie along range roads and township roads.

The drive was a series of long droning cruises punctuated by sharp right-angle corners.

It is noted for its unusual characteristic of not having right-angle corners, providing a challenge to bowlers when lining the rinks up correctly.
