Yes, you are correct. Latitude lines, also known as parallels, measure the distance in degrees north and south of the Equator. The Equator is a horizontal line that encircles Earth at its midpoint, dividing the planet into the Northern Hemisphere and the Southern Hemisphere. It is designated as 0 degrees latitude. As you move north from the Equator, the latitude lines increase in value, reaching a maximum of 90 degrees at the North Pole. Similarly, as you move south from the Equator, the latitude lines decrease in value, reaching a maximum of -90 degrees at the South Pole. So, the Equator serves as the reference point for measuring latitude.
