A Speed Square, also generically called a rafter square, rafter angle square, and triangle square, is a multi-purpose triangular carpenters' tool used for marking out. Its functions encompass many of those offered by combination squares , try squares , and framing squares .
This implies that the vertical scale factor, h, equals the horizontal scale factor, k. Since k = sec φ, so must h. The graph shows the variation of this scale factor with latitude. Some numerical values are listed below. at latitude 30° the scale factor is k = sec 30° = 1.15, at latitude 45° the scale factor is k = sec 45° = 1.41,
The cones are distinctive, superficially resembling small globe artichokes, 4–7 cm long and 4–6 cm broad, with pointed triangular scales; they mature about 7 months after pollination, when (like fir and cedar cones) they disintegrate to release the winged seeds.
