Which map projection class has longitude lines appearing as straight, equally spaced parallel lines and latitude lines appearing as parallel lines that intersect the meridians at right angles?

Cylindrical projection

Explanation:

Characterics of cylindrical map projection

Lines of latitude and longitude are parallel intersecting at 90 degrees

Meridians are equidistant

Forms a rectangular map

Scale along the equator or standard parallels (lines of tangency) is true

Can have the properites of equidistance, conformality or equal area

The poles are represented as lines
