 comparison of two quantities ratio statement that two ratios are equal proportion when you set three or more ratios equal extended proprtion "the product of the extremes is equal to the product of the means." Cross-Product Property the scale compares each length in the drawing to the actual length scale drawing how are polygons similar? 1.corresponding angles and congruent 2. corresponding sides are proportional ratio of the lengths of corresponding sides similarity ratio you can use similar triangles and measurements to find distances that are difficult to measure directly indirect measurement perpendicular segment from a vertex to the line containing the opposite side altitude for any two positive numbers a and b, the ? of a and b is the positive #x such that a/x = x/b geometric mean # of square units a surface covers area quadrilateral with both pairs of opposite sides parallel parallelogram parallelogram with four sides congruent rhombus parallelogram with 4 right angles rectangle parallelogram with 4 congruent sides and 4 right angles square quadrilateral with 2 pairs of adjacent sides congruent and no opposite sides congruent kite quadrilateral with exactly one pair of parallel sides trapezoid trapezoid whose nonparallel opposite sides are congruent isosceles trapezoid Properties of Parallelograms 1. opposite angles congruent 2. diagonals bisect each other 3. consecutive angles = 180 4. opposite sides congruent 5. diagonal bisect opposite angles 6. diagonals perpendicular 7. diagonals congruent segment that joins the midpoints of the nonparallel sides midsegment a statement that follows immediately after a theorem corollary CPCTC corresponding parts of congruent triangles are congruent states that if a point is on the bisector of an angle, then it is equidistant from the sides of the angle Angle Bisector Theorem 1. some rectangles are squares 2. no kites are parallelograms 3. some trapezoids have a pair of congruent sides 4. all squares are regulare quadrilaterals 5. no trapezoids have both pairs of opposite sides parallel 6. some rectangles are rhombi 7. some rhombi have congruent diagonals 8. all square are parallelograms
