EASY BRAINLIEST!! Which step is the same in the construction of a perpendicular line through a point on a line and the construction of a perpendicular line through a point off a line?

Create only one arc on the original line.

Create two arcs on the original line.

Place the compass on a point off the original line.

Place the compass on a point on the original line.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
