Answer:
As this triangle is being transformed by rotation, the angles will stay same as well as the  sides and other details, if you are doing this on a coordinate plane, then the points of the triangle would be changed and nothing else

Answer: Correct
Step-by-step explanation:
The conclusion is valid. Since 
 and 
, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since 
, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.

Answer:
11.2 units
Step-by-step explanation:
From (-7, -7) to (-2, 3) is 5 units horizontally  and  10 units vertically.  Thus we have a right triangle with sides 5 and 10 respectively.  The length of the hypotenuse of this triangle is the distance between (-2, 3) & (-7, -7):
d = √(5² + 10²) = √(25 + 100) = √125 = √25√5, or 5√5.
This is approximately 11.2 units
