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

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

definition of a rectangle a quadrilateral with four right angles

rectangle theorems if 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 rectangle opposite 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 rhombus a quadrilateral with four congruent sides

rhombus theroems the 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 rhombus all parallelogram properties apply; all four sides are congruent; diagonals are perpendicular; the diagonals bisect opposite angles

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

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

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

definition of an isosceles trapezoid a trapezoid with the legs congruent

isosceles trapezoid theroems both pairs of base angles are congruent; the diagonals are congruent

trapezoid median theorem the 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 other paralellogram, rectangle, rhombus, square

in these quadrilaterals, the diagonals are congruent rectangle, square, isosceles trapezoid

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

in these quadrilaterals, the diagonals are perpendicular rhombus, 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 sides rhombus, square

these quadrilaterals always have all four right angles rectangle, square

these quadrilaterals always have perpendicular diagonals rhombus, 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

Answer:

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.

Answer:

$7.65

Step-by-step explanation:

Okay, this is a standard multiplication problem, so:

4 1/2 x 1.7 = 7.65

Polly will spend $7.65 on pink fabric

hope this helps:)

Answer:

$7.65

Step-by-step explanation:

cost for 1 yard=$1.70

cost for 1/2 yard=$0.85

so cost for 4 and half yard will be

 = 4*1.70+0.85

=6.8+0.85

=$7.65

Answer:

1. No, Lin is incorrect. If you change both numbers to regular notation, you get that Panama has 4,000,000 residents, and Thailand has 70,000,000 residents. 4 million times 20 is 80 million, not 70 million.

2. 10^8. You need to put 10 to the 8th power because 1 × 10^7 is too little, so it is the next power to use that isn't too small

3. Label each increment 10^7, 2 × 10^7, 3 × 10^7... 9 × 10^7, 10^8.

4. Panama's point would be located 2/5 of the way between 0 and 10^7. Peru's point would be located 1/5 of the way between 3 × 10^7 and 4 × 10^7. Thailand's point would be located right on 7 × 10^7.

Answer:

12.79%

Step-by-step explanation:

Let :

Great grand mother = 86 years

Jenny = 11 years

Let the percentage = x

x % of great grandmother's age = Jenny's age

x% * 86 = 11

x/ 100 * 86 = 11

86x / 100 = 11

86x = 100 * 11

86x = 1100

x = 1100/86

x = 12.79

x = 12.79%

Answer:V= 1526.8m3

Step-by-step explanation: pi (9)2(6)

A cylinder is a three-dimensional structure formed by two parallel circular bases. The volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.

Given the height of the cylinder is 6m, while the base diameter is 18m. Therefore, the volume of the cylinder can be written as,

Volume of cylinder = (π/4)×d²×h = (π/4)×18²×6 = 1526.814m³

Hence, the volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

Answer:

B. function 13 meters per second

Step-by-step explanation:

Answer:

B) Function A; 14 mps

Step-by-step explanation:

Function B has a speed of 13/s

If you look at Function A and divide the right column by the corresponding values in the left column, you get 14 every time. That is the rate of Function A.

14>13.. so Function A is faster

Answer:

(10/3, 1)

Step-by-step explanation:

Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)

The formula for calculating the coordinate of a point divided in the ratio a:b is expressed as;

X = ax1+bx2/a+b

Y = ay1+by2/a+b

Given the coordinates A(4,4) B(2,-5) divided in the ratio 2:1

X = 2(4)+1(2)/2+1

X = 8+2/3

X = 10/3

Similarly;

Y = 2(4)+1(-5)/2+1

Y = 8-5/3

Y = 3/3

Y = 1

Hence the required coordinate is (10/3, 1)
