Answer:
rotational symmetry; the rotation of 180 degrees around the point (1, 1) maps the parallelogram onto itself.
Step-by-step explanation:
Answer:
s ∈ (25.5,34.5)
''s'' is in inches unit
s ∈ IR
Step-by-step explanation:
We know that the perimeter of a square is
Where P is the perimeter and s is the length of a side.
We want the perimeter to be greater than 102 inches but less than 138 inches.
We can write :
102 inches < P < 138 inches
If we replace P = 4s in the expression :
102 inches < 4s < 138 inches
Dividing by ''4''
25.5 inches < s < 34.5 inches
If we want the perimeter to be greater than 102 inches but less than 138 inches the length of a side must be greater than 25.5 inches but less than 34.5 inches.
Writing this in interval notation
s ∈ (25.5,34.5)
s ∈ IR
4 i
I is the square root of negative one
The orthocenter of an obtuse triangle always lies : C. On the outside of the triangle
<span>Attitude of an obtuse triangle will not go through the midpoint line of the triangle and the three points of the triangle will intersect with each other at some point, so it must lies outside of the triangle</span>
