Answer:
BK=9
Step-by-step explanation:
A midsegment is one half of the length of the base. So, If the base, which is ST is 18, the midsegment will be 18/2=9
Answer: a) 
Step-by-step explanation:
We know that the volume of an oblique pyramid is given by :-

If the volume of an oblique pyramid with a square base is V units³ and the height is h units.
Then, we have

Multiply 3 on both sides , we get

Divide both sides by h , we get

i.e. 
Hence, the expression represents the area of the base of the pyramid = 
Hence, the correct answer is a) 3 v/h units^2

Answer:
1) Congruent
2) Supplementary
3) Congruent
4) Congruent
Step-by-step explanation:
1) The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .
2) Formally, we can say that if two lines are parallel, then consecutive interior angles are supplementary. We refer to this as the consecutive interior angles postulate.
3) When the lines are parallel, the corresponding angles are congruent . When two lines are cut by a transversal, the pairs of angles on one side of the transversal and inside the two lines are called the consecutive interior angles.
4) The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate exterior angles are congruent.
