Three parallel lines in a plane are intersected by a fourth line, forming twelve angles.
If one of the angles has measure
how many of the other eleven angles have
measure
Correct Answer:
Explanation:
Drawing the figure described in the problem will help you visualize the
correct solution to the problem. The figure below shows three parallel
lines intersected by a fourth line. The acute angle is labeled
as
shown below.
Using the fact that vertical angles and alternate interior angles are equal, you can put
a check showing the other angles in the figure that also measure
as shown
below.
There are 5 other angles that measure
Therefore, the correct answer to this problem
is 5. The number 5 can be gridded in any of the four columns on the answer grid.
