Which lines of longitude and latitude vary in length?
-- All meridians of longitude have the same length ... they all join the north and south poles. -- Each parallel of north latitude has the same length as the parallel at the equal south latitude, but no other one.
Why aren't all parallels equal in length like meridians are?
There's a simple answer: The earth is a sphere and the parallels are, well, parallel to each other. So obviously the ones closer to the poles are shorter than the ones closest to the Ecuator. As for the meridians all meet at one point ehich are the poles, so they are all the same length.
Why was it necessary to specify a particular meridan when determining the length of a meter?
I don't see the need for that - all meridians (for example, at sea level) should have the same length.
What is a triangle with all three sides are equal length?
If all three sides are equal in length, the triangle is said to be Equilateral.
Are any of a octagons sides equal in length?
They can be. A regular octagon has all sides of equal length.

Which is true about lines of longitude?
Every meridian of constant longitude is nominally a semi-circle, equal in length to all other meridians, and joining the Earth's north and south poles.
Lines of longitude called what?
Meridians of longitude; parallels of latitude. Remember that meridians are all the same length (20,000 km) and that they meet at the poles. Parallels are, well, parallel, and are different lengths, the longest being the Equator.

What is the hemisphere is tilted toward the sun during the vernal equinox?
Neither. All days are equal length.
Are all 4 sides equal in length on a rhombus?
Yes, all four sides of a rhombus are of equal length.
Where do all meridians meed?
All meridians of longitude converge (meet) at the north and south poles.
What is a triangle with all three sides are equal length?
If all three sides are equal in length, the triangle is said to be Equilateral.
Are any of a octagons sides equal in length?
They can be. A regular octagon has all sides of equal length.
Is an equilateral trianglewith all sides equal in length?
Yes the 3 sides are equal in length.
Which direction do Yin meridians flow?
Of the twelve regular meridians, the yin meridians always flow up the body, and all the yang meridians always flow down.
