Drill Size = Major Diameter - (.975 divided by the number of threads per inch). For example, with a 1/4-32 tap, .250 - .0305 = .2195 (7/32 or #2 drill size). Metric tap drill sizes are the diameter minus the pitch (For example, 42mm x 1.5 tap uses a 40.5 drill). Follow these links to browse our taps and die selection:
It is easy to construct a concave figure if the figure has at least 4 sides Just make sure that one interior angle is bigger than 180 degrees. In other words, an interior angle should be a reflex angle Why am I saying at least 4 sides? It is possible to make a concave triangle? The answer is no! Since the sum of the interior angles in any triangle must add up to 180 degrees, no interior angles can be more than 180. It is impossible! Buy a comprehensive geometric formulas ebook.
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. (non-adjacent interior angles may also be referred to as remote interior angles).hen, using the first theorem above, set the exterior angle (x) equal to the sum of the two non-adjacent interior angles which are 45Â° and 72Â°. x = 45 + 72 x = 117. So, an exterior angle at P measures 117Â°.
