3)the line G & H are parallel
4) Parallel line theorem is what I do believe it's called (do you have choices for this one?)
X=7 What you can do is look at the first two values given, and make them x1 and y1. Then your next value here is y2.
So x1 is 14, and y1 is 3. y2 becomes 6. X2 is unknown.
Then make the formula: x1/y2 is equal to x2/y1
(You are setting two fractions equal to each other)
That makes 14/6=X/3. When we cross multiply, we find that x=7.
You can draw the 3 rectangles with these measurements then divide one horizontally one vertically and one slanted from one top corner to one bottom corner
