Which description does NOT guarantee that a quadrilateral is a rectangle?

Mathematics
1 answer:
Kisachek [45]3 years ago
8 0

Answer: A

 a quadrilateral with all four angles right

Step-by-step explanation:

A  quadrilateral is a rectangle if a quadrilateral has all four angles right,

a parallelogram with congruent sides

a quadrilateral with diagonals that are congruent and bisect each other

a quadrilateral with all congruent angles. Because a rectangle possesses 2 pairs of parallel sides, 4 right angles at 90°. It has opposite sides which

are parallel and  congruent. And all its angles are congruent.

But a quadrilateral with all four angles right is a description that does NOT guarantee that a quadrilateral is a rectangle. Because this description is also applicable to a square.

assume a telephone signal travels through a cable at two-thirds the speed of light. how long does it take the signal to get from
Helen [10]

The time length for a sign to travel from new york to Miami is 0.089 seconds.

We understand the speed of mild in miles per 2nd is 186,000.

the rate of smartphone signal is 2/3rd is =2/3rd of 186,000

                                                                     = 124,000 miles in line with 2nd

Distance among Miami and new york is given to be 1100 miles.

So, the time required to journey the phone signal from new york city to Miami is = distance ÷ speed

              = 1100 ÷ 124,000

              =0.089 seconds

Time taken via the telephone sign from Miami to new york is 0.089 seconds.
