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.
