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°
Interior angles (angles on the inside) sum up to 180Â° more; Triangle Inequality Theorem: This theorem states that the sum of the lengths of any 2 sides of a triangle must be greater than the third side. more; Relationship between measurement of the sides and angles in a Triangle: The largest
