1/2.
What are bisecting lines?
Lines that cut one another.
Lines that are long.
Lines that never touch.
Given that l₁ and l₂ are parallel lines in the figure, and I₃ is a transversal with angle b = 85°,the value of angle a is:
85°.
95°.
125°.
175°.
What are perpendicular lines?
None is correct.
Lines that intersect to form a right angle at the point of intersection.
Lines that will cut other lines (usually parallel lines) at an angle other than right angle.
All are correct.
