Answer: The answer is six.
Step-by-step explanation: There are six important properties of a parallelogram. Please see the attached figure. The properties are as follows :
(i) The opposite sides of a parallelogram are parallel and congruent, i.e., PQ║RS, QR║PS, PQ ≅ RS and QR ≅ PS.
(ii) The opposite angles of a parallelogram are congruent, i.e., ∠P = ∠R and ∠Q = ∠S.
(iii) The diagonals of a parallelogram bisect each other, i.e., OP = OR and OQ = OS.
(iv) Consecutive angles of a parallelogram are supplementary. For example, ∠P + ∠Q = 180°.
(v) If one angles of a parallelogram is 90°, then all the angles are 90°.
(vi) Each diagonal of a parallelogram separates it into two congruent triangles. For example, ΔPQR ≅ ΔSQR.
Answer:
B
Step-by-step explanation:
The formula for the area of a triangle is given as:
A = ½*base*height
A = ½*b*h
A = (bh)2
If we know the area (A) and the base, to find the height, the following would be done:
Divide both sides by b
A/b = h/2
Multiply both sides by 2
As we can see here, to find the base, we would divide the area by the vase, then multiply what we get by 2.
