the distance formula to find the length of the sides... opposite sides equal it could be a rectangle or parallelogram all sides equal, square or rhombus adjacent equal, kite and then the slope is used to check angles if the product of the 2 lines in -1 the lines are perpendicular (right angle) the the slopes of 2 lines are the same the sides are parallel.
I think this is it ^_^
Answer:
-6/7
Step-by-step explanation:
Slope is negative, around -1
Answer:
Step-by-step explanation:
By definition we know that
and
As 
Then
Now square both sides of the equation:
In the second quadrant sin (t) is positive. Then we take the positive root
5,000-500-50-5 they are not all the same value.
