A location in space - a dot on a piece of paper

### Line

Connects two points via the shortest path and continues indefintely (forever) in both directions

### Line Segment

Part of a line between two points

### Perpendicular Line Segment

Line Segments that intersect (cross) at an angle of 90°

### Parallel Line Segments

Line segements that never intersect (they are always the same distance apart)

### Right Angle

An angle that measures 90°

### Acute Angle

An angle that measures less than 90

### Obtuse Angle

An angle that measures more than 90°

### Vertex

Point at which two line segments intersect (forming an angle)

### Scalene Triangle

A triangle with all three sides with different lengths

### Isosceles Triangle

A triangle with two equal length sides (and two equal internal angles)

### Equilateral Triangle

A traingle with all three sides of equal length (each internal angles = 60°)

Distance (line segment) from center of a circle to any point on that circle's circumference.

### Diameter

A line segment (or length) joining two points on a circles circumference and passes through the circle's center (twice the length of the radius)

### Circumference

Distance around a circle (the perimeter)

### Chord

A line segment joining two points on a curve
