Answer: C

Question. If two lines intersect, they form how many angles?
(a) Two
(b) Three
(c) Four
(d) Five

Answer: C

Question. Adjacent angles formed by two lines intersecting each other, like angle 'a' and angle 'b', they are called a linear pair. The sum of these linear pairs always is
(a) 90 degrees
(b) 120 degrees
(c) 180 degrees
(d) 360 degrees

Answer: C

Question. Vertically opposite angles formed by two intersecting lines are always
(a) Complementary angles
(b) Always 90 degrees
(c) Equal to each other
(d) Sum up to 180 degrees

Answer: C

Question. What are angles that lie opposite to each other when two lines intersect called?
(a) Adjacent angles
(b) Linear pairs
(c) Alternate angles
(d) Vertically opposite angles

Answer: D

Question. If angle 'a' and angle 'b' form a linear pair, and the value of angle 'a' is 120 degrees, then the value of angle 'b' must be
(a) 120 degrees
(b) 180 degrees
(c) 60 degrees
(d) 90 degrees

Answer: C

Question. When two lines intersect and all four angles formed are equal, then each angle must be a right angle, which is how many degrees?
(a) 45 degrees
(b) 180 degrees
(c) 90 degrees
(d) 60 degrees

Answer: C

Question. A pair of lines which intersect each other at right angles is called
(a) Parallel lines
(b) Transversals
(c) Vertically opposite lines
(d) Perpendicular lines

Answer: D

Question. Lines that lie on the same plane and do not meet however far we extend them, this pair of lines is called
(a) Intersecting lines
(b) Perpendicular lines
(c) Parallel lines
(d) Straight lines

Answer: C

Question. When one line intersects two different lines, this intersecting line is called
(a) Linear pair
