1 pound 16 ounces 1 gallon 8 pints 4 quarts 1 gallon 1 yard 3 feet 1 ton 2000 pounds Perimeter of Rectangle 2 (L) + 2 (W) Area of a Circle Pi x Radius2 Circumference of a Circle 2 x Pi x Radius Area of Rectangle L x W Percent Decrease x/100 = Difference/ Original Price; Original Price is larger number Percent Increase x/100 = Difference/Original Price ; Original Price is smaller number Find Distance D = R x T Interest P x R x T ; Principal interest x Interest x Time Zero Power always equals 1 Trapezoid Have exactly two sides that are parallel. Two parallel sides of trapezoid is bases. A=1/2 (Sum of the lengths of the bases) (height) Parallelograms Have opposite sides that are parallel, and their opposite sides and angles are equal. The angles don't have to be right angles. A=(base)(height) Rhombuses Have four sides of equal length, but the angles don't have to be right angles. Perimeter= 4(s) Supplementary Angle Two angles that equal 180 when added together Obtuse Angle More than 90 degrees but less than 180 degrees Acute Angle Acute angle is more than less than 90 degrees Straight line equal 180 degrees Right Angle Is exactly 90 degrees Similar triangles have the same shape, but they may be different sizes. Isosceles triangle A triangle that has two equal sides. Not only are two sides equal, but the angles opposite the equal sides, called base angles are also equal. Radius Straight line distance form its Center to any point on the circle. Chord Line segment that connects any two points on a circle Diameter A chord that passes through the Center of circle Circumference is the distance around the circle Volume of a rectangular solid or box L x W x H Surface area of a rectangular solid or box 2(lw) + 2(wh) + 2(lh) Volume of Cylinder Find the area of its base and the height Line segment is a piece of a line, and it has an exact measurable length. Vertical angle angles across the vertex from each other and are equal to each other Midpoint The point exactly in the middle of a line segment, halfway between the endpoint Bisect To cut in half so the midpoint of a line segment bisects that line segment
