definition of a parallelograma quadrilateral with both pairs of opposite sides parallel

five properties/theorems for parallelogramsopposite sides are parallel, diagonals bisect each other, opposite sides are congruent, opposite angles are congruent, consecutive angles are supplementary

definition of a rectanglea quadrilateral with four right angles

rectangle theoremsif a parallelogram is a rectangle, then its diagonals are congruent; if the diagonals of a parallelogram are congruent, then the paralellogram is a rectangle

five properties of a rectangleopposite sides are congruent and parallel; opposite angles are congruent; consecutive angles are supplementary; diagonals are congruent and bisect each other; all four angles are right angles

definition of a rhombusa quadrilateral with four congruent sides

rhombus theroemsthe diagonals of a rhombus are perpendicular; if the diagonals of a parallelogram are perpendicular, then the paralellogram is a rhombus; each diagonal of a rhombus bisects a pair of opposite angles

properties of a rhombusall parallelogram properties apply; all four sides are congruent; diagonals are perpendicular; the diagonals bisect opposite angles

definition of a squarea quadrilateral with four right angles and four congruent sides

properties of a squarethe properties of a rectangle plus the properties of a rhombus; four right angles; all four sides are congruent

definition of a trapezoida quadrilateral with exactly one pair of parallel sides

definition of an isosceles trapezoida trapezoid with the legs congruent

isosceles trapezoid theroemsboth pairs of base angles are congruent; the diagonals are congruent

trapezoid median theoremthe median of a trapezoid is parallel to the bases and its measure is one-half the sum of the measures of the bases, or median=1/2(x+y)

in these quadrilaterals, the diagonals bisect each otherparalellogram, rectangle, rhombus, square

in these quadrilaterals, the diagonals are congruentrectangle, square, isosceles trapezoid

in these quadrilaterals, each of the diagonals bisects a pair of opposite anglesrhombus, square

in these quadrilaterals, the diagonals are perpendicularrhombus, square

a rhombus is always a...parallelogram

a square is always a...parallelogram, rhombus, and rectangle

a rectangle is always a...parallelogram

a square is never a...trapezoid, because trapezoids only have one pair of parallel sides

a trapezoid is never a...parallelogram, rhombus, rectangle, or square, because trapezoids only have one pair of parallel sides

these quadrilaterals always have all four congruent sidesrhombus, square

these quadrilaterals always have all four right anglesrectangle, square

these quadrilaterals always have perpendicular diagonalsrhombus, square

if you divide a square into four right triangles by drawing its two diagonals, the measure of each of the angles in the triangles that is not a right angle is...45 degrees

the diagonals of a rhombus...are not always congruent, but they are always perpendicular and they do always bisect each other, and they do always bisect the pairs of opposite angles

the diagonals of a rectangle...are not always perpendicular, but they are always congruent and they always bisect each other

the diagonals of a parallelogram...always bisect each other

squares, rectangles, trapeziods (only if isoceles)

Step-by-step explanation:

Squares are rectangles and rectangles always will have diagonals that are congruent. Trapezoids, if isoceles, will have congruent diagonals.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
