By taking the inverse tan, we get:

The statement which the diagram shows is that the length of GH is half of the length of KL . Option B
<h3>What is the midsegment theorem?</h3>
The midsegment theorem holds that any segment that forms the joining midpoints of two sides of a triangle is parallel to half the length of the third side.
It can be seen that the length of GH is half of the length of KL as deduced from the diagram
Therefore, the statement which the diagram shows is that the length of GH is half of the length of KL . Option B
