- Line
A line is a general term for straight lines (hence its name) that extend from a specific point on the triangle.
- Height
Height is a line that extends from a specific vertex and reaches perpendicularly to the opposite side, creating a right angle. The height is marked with the letter h (from the word height).
- Median
The median is also a line extending from a specific vertex to the opposite side, but it reaches exactly the middle of the opposite side and divides it into two equal parts.
- Angle Bisector
An angle bisector is a line that extends from a specific vertex and actually divides the vertex into two equal angles.
- Perpendicular Bisector
A perpendicular bisector is a line that extends from the middle of a side perpendicular to it.
- Midsegment
A midsegment is a line that connects the midpoints of two sides and is parallel to the third side, with its length being half of it.
- Opposite Side
An opposite side is the side that is located opposite to a specific vertex and does not pass through it.
