The lines are perpendicular.
Point is not an undefined term. It can be defined as a mathematically precise location, or as the place where two lines intersect.
There are 90 degrees in a left angle as there are in a right angle but the term 'left angle' is rarely used
The answer to this question...MedianExplanation: Medians in triangles are the lines that are at the midpoint of one line and pass through the vertici (I can't spell it right) on the other side. The vertici being the opposite angle.
A geometric term is a term of geometry.
There isn't a specific name for 45 degrees, like when 90 degree angle is called a "right angle". However, there is a general term for any angle less than 90 degrees - "acute angle". Here's a full list: < 90 degrees = acute 90 degrees = right angle between 90 & 180 degrees = obtuse 180 degrees = straight line between 180 & 360 degrees = reflex 360 deg = revolution (because it turns in a complete circle)
Perpendicular lines that that intersect at 90 degrees are right angles.
It is a perpendicular line that intercepts another line at 90 degrees.
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
Perpendicular lines are two lines that intersect to form four right angles.
Two lines that intersect and form 90-degree angles (right angles) are "perpendicular" to each other. You would call them "perpendicular lines."
Perpendicular refers to two lines or surfaces that intersect at a 90-degree angle, forming a right angle. It is a geometrical term used to describe a relationship between two objects that are perpendicular to each other.
"Prependicular" seems to be a typographical error or a misinterpretation of the term "perpendicular." Perpendicular refers to two lines or surfaces that meet or intersect at a right angle (90 degrees). In geometry, if one line is perpendicular to another, it means they are oriented in such a way that they form a right angle with each other.
If they intersect they are refered to as skew lines and if the do not the term for this is that they are parallel lines.
Skew lines are a term for lines in geometry. They mean two lines that are not parallel, but do not intersect either. It is only possible in three dimensions and up.

It is the incentre.
