|KEY WORD : architecture / general terms|
| The 45
degree pitch of the hypotenuse, the side opposite the right angle, of an
isosceles right-angled triangle. A right angle itself is called chokkaku
直角, or *kane-no-te 矩の手.
In Japanese architecture, the slope of roofs vary. When viewed from the
exterior the structural degree of pitch can be fairly well ascertained,
on tiled roofs but heavily thatched roofs *kayabuki
yane 茅葺屋根 or thickly shingled roofs *kokerabuki 柿葺 tend to disguise the actual structural pitch.
