What do the four figures below have in common?
Upon observation we can see that all the lines form a right angle of 90 degrees with each other.
Typically lines that form a right angle of 90 degrees with each other are perpendicular and vertical lines.
Therefore, the correct answer is a.
All the figures are perpendicular
The lines below are not the same size, but are they parallel?
Look for the square corner symbol or lines that meet at what appears to be a 90-degree angle. In these figures, you can see the lines intersect to form right angles, not acute or obtuse angles.
Perpendicular lines intersect at 90 degrees, while parallel lines never intersect at all - they stay the same distance apart forever. These figures show intersecting lines, so they can't be parallel!
No! They can have different orientations but still share the same mathematical property. Here, all four figures show perpendicular lines even though they're positioned differently.
An acute angle is less than 90 degrees, and an obtuse angle is greater than 90 degrees. All these figures show exactly 90-degree angles, which are called right angles - the defining feature of perpendicular lines.
Yes! Perpendicular lines can be horizontal and vertical like a plus sign, or diagonal like an X. What matters is that they meet at exactly 90 degrees, regardless of their orientation.
