B
Contour lines.
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
A line segment would connect two points on a plane.
A chord
Two points with a single line connecting them.
isohyet
Contour lines.
x and y axis
That's called an isobar.
Isotachs
On a Weather Map, the lines connecting points of equal temperature are called Isotherms.Similarly, the lines that connect points of equal barometric pressure are called Isobars.
meridian
On a Weather Map, the lines connecting points of equal temperature are called Isotherms.Similarly, the lines that connect points of equal barometric pressure are called Isobars.
isolines
On a Weather Map, the lines connecting points of equal temperature are called Isotherms.Similarly, the lines that connect points of equal barometric pressure are called Isobars.
The line connecting the points is called a chord; the part of the perimeter of the circle enclosed is called an arc; the area between an arc and the chord is called a circular segment.
The answer is very simple it's an isotherm map because an isobar map are lines that connect areas of the same pressure therefore lines that connect areas of the same temperature is and isotherm map
