After it dried, which took about two hours, I sanded it flush with the wood using #120-grit sandpaper, then stained the entire shelf. You have to look closely to see the spot where the nail hole had been! Quick Tip: Always sand in the direction of the grain of the wood to avoid unsightly scratches.
Angle Sum Theorem. The Angle Sum Theorem gives an important result about triangles, which is used in many algebra and geometry problems. We give the proof below. Theorem: The sum of the measures of the interior angles of a triangle is 180 Â°. Given: Î X Y Z. Prove: m â  1 + m â  2 + m â  3 = 180 Â°
the sum interior Si of the measures of the angles of a polygon with n sides is given by the formula Si=(n-2)180 exterior angle sum if 1 exterior angle is taken at each vertex, the sum exterior(Se) of the measures of the exterior angles of a polygon is given by the formula (Se)=360 the number (d) of diagonals that can be drawn in a polygon of n sides is given by what formula
