Question

Perpendicular lines intersect to form four right angles. never always sometimes

Answer 1

Perpendicular lines intersect to form four right triangles: Always.

Answer 2

Always

Explanation:

The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.
