Answer: SECOND OPTION.

Step-by-step explanation:

By definition, the slopes of parallel lines are equal.

The slope of a line can be found applying this procedure:

1. Choose two points on the line.

2. Substitute the coordinates of each point chosen into the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

3. Evaluate in order to find the slope.

A parallelogram is a quadrilateral whose opposite sides are parallel and have equal length.

Let's assume that  that BC and AD have equal length and CD and BA have equal length. Then:

1. If you calculate the slope of BC and the slope of AD and they are equal, then BC and AD are parallel.

2. If find the slope of CD and the slope of BA and they are equal, then CD and BA are parallel.

Therefore ABCD is a parallelogram.

How many equilateral triangles with sides of 4 can fit into a larger triangle with sides of 2012
igomit [66]
The base measures 2012 if you divide that by four you get 503 trianles on the bottom and on the sides and each one gets one smaller until you get to one so 503+502+501,.... or 252+251(504) so the answer is 126,756 triangles in total because 1+503=504  2+502=504... when you get to 252 you just add that to itself so that is the odd one out
