zlopas [31]

Answer:

There are a number of ways to show whether a quadrilateral placed on a coordinate plane is a parallelogram or not. Here are a few ways:

1. Show that both pairs of opposite sides are congruent.  

2. Show that both pairs of opposite sides are parallel

3. Show that a pair of opposite sides are congruent and parallel

4. Show that the diagonals bisect each other.

Elina [12.6K]

Answer:

The real-life distance to the nearest mile between Tampa and Orlando is 88 miles

Step-by-step explanation:

String distance between Fort Myers and Miami = 7 inches

A real life distance between Fort Myers and Miami = 154 miles

So, 7 inches = 154 miles

1 inch = \frac{154}{7}=22 miles

Scale : 1 inch = 22  miles

String distance between Tampa and Orlando = 4 inches

Using scale

The real-life distance to the nearest mile between Tampa and Orlando = 4 \times 22 = 88 miles

Hence The real-life distance to the nearest mile between Tampa and Orlando is 88 miles
