Two congruent squares are shown in Figures 1 and 2 below. I need answer quick!

The combined area of the shaded triangles in Figure 1 is equal to the combined area of the shaded triangles in Figure 2.  The area of the unshaded square in Figure 1 can be represented by 4c. The combined area of the two unshaded squares in Figure 2 can be  4a+4b. The areas of the squares in Figure 1 and Figure 2 show that 4a+4b=4c.

Step-by-step explanation:

iReady math diagnostic.

the 3rd on is correct

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
