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°
Which statement regarding the interior and exterior angles of a triangle is true? An exterior angle is supplementary to the adjacent interior angle. An adjacent interior angle is supplementary to a remote interior angle. A remote interior angle is congruent to the exterior angle. An exterior angle is supplementary to the remote interior angle.
