In drawing B, we observe two right angles, which teaches us that they are practically equal. From this, we can conclude that they are corresponding angles, located at the intersection of two parallel lines.
In drawing A, we only see one right angle, so we cannot deduce that the two lines are parallel.
Answer
B
Exercise #2
Which lines are perpendicular to each other?
Video Solution
Step-by-Step Solution
Let's remember that perpendicular lines are lines that form a right angle of 90 degrees between them.
The only drawing where it can be seen that the lines form a right angle of 90 degrees between them is drawing A.
Answer
Exercise #3
What can be said about the lines shown below?
Video Solution
Step-by-Step Solution
Let's remember the different properties of lines.
The lines are not parallel since they intersect.
The lines are not perpendicular since they do not form a right angle of 90 degrees between them.
Therefore, no answer is correct.
Answer
None of the above.
Exercise #4
What do the four figures below have in common?
Video Solution
Step-by-Step Solution
Answer
All parallel
Exercise #5
Which of the figures shows parallel lines?
Video Solution
Step-by-Step Solution
Parallel lines are lines that, if extended, will never meet.
In the drawings A+B+D if we extend the lines we will see that at a certain point they come together.
In drawing C, the lines will never meet, therefore they are parallel lines.
