<span>In geometry, definitions are formed using known words or terms to describe a new word. There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane. Undefined terms have not been defined, and defined are answered. They are terms that have a relationship with the point od discussion. :)</span>
Answer:
1
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 4-2)/(1 - -1)
= (4-2)/(1+1)
= 2/2
= 1
For the square area we have:
12.12=144
and for the rectangle we have:
4.11=44
