A wire of length 3x is bent into the shape of a square Express the area A of the square as a function of x?
The square is formed from a wire the length of 3x, which forms a perimeter of the same length. Because each side of the square is one fourth of the total perimeter (1 out of 4 equal sides), each side is 3x/4. The square of one side of a square is equal to the area of that square, so the area is (3x/4)2 = (9/16)x2.The answer is then A = (9/16)x2.
Two lines that lie in the same plane and are always the same distance apart?
parallel lines
Are skew lines parallel?
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
Is 6 symmetrical?
no ****************** Draw a vertical line through the centre of the number 6. As both sides are not identical, then there is no symmetry. Do the same with a capital H, and there is symmetry, as both sides of the vertical line are identical.
Show that sin x equals cos x for some angle t between 0 and 90?
sin(x) = cos(x)sin(x)/cos(x) = tan(x) = 1x = arctan(1) = 45 degreessin(45)=cos(45) = Sqrt(2)/2 Answer: By observation. Since Sine = Opposite over hypotenuse and Cosine = Adjacent over hypotenuse. Any right angle triangle where the opposite and adjacent sides are the same length will have Sine equal to Cosine. This only happens with an isosceles triangle (two sides are equal in length). When one angle is 90o the other two are 45o.
Does each side of a shape have to be the same length to be parallel?
No. The sides of a shape don't need to be equal in length to be parallel.

What is a square shape?
A four sided figure with all sides the same length and opposite sides parallel.
What shape has pairs of sides next to each other and have the same length and there are no parallel sides?
triunghiul echilateral
A shape with no right angle with a reflex angle four sides two parallel sides and have the same lenght?
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.

A kite
What is a shape with 4 sides of the same length parallel to each other called?
A square or a rhombus
