<span>A square will always be a parallelogram due to the definition of a square.
A parallelogram is a quadrilateral with two pairs of parallel lines. Each two opposite sides are equal and none of the angles is right.
A square is a quadrilateral with 2 pairs of parallel sides, all right angles and all congruent sides.
Since it is part of the definition, it is impossible to have a square that is not a parallelogram.</span>
Answer:
a= 6 7/8
Step-by-step explanation:
If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
Answer: Each triangle:40 cm²
Kite : 80cm²
Step-by-step explanation:
The area of a triangle is
1/2bh
The height of the triangle is
h=1/2(10)=5cm
and the base is 16 cm.
The area of each triangle is
= 1/2(16)(5)=40cm^2
2. The total area of the kite is 2 times the area of one triangle.
= 2*40=80cm^2
