perpendicular
yes
an angle is made from 2 lines so a circle does not have angles
An angle is made of 2 lines but aside is made of 1 line
It has 2
perpendicular
the lines are perpendicular, which basically means the two lines intersecting form a right angle
"right angle" is two lines that intersect at 90 degrees "acute angle" is when 2 lines meet at less than 90 degrees "obtuse angle" is when lines meet at an angle more than 90 degrees , a straight angle is when 2 lines meet at exactly 180 degrees.
yes
Because a right angle has to have 2 lines.
an angle is made from 2 lines so a circle does not have angles
An angle is made of 2 lines but aside is made of 1 line
That's the "vertex" of the angle.
Two identical lines that are exactly the same. Regardless of position or angle.
point of intersection of 2 straight lines.
It has 2
Two perpendicular lines will meet in a right angle (90 degrees) if they exist on a flat plane.
