100
Collinear
This describes points that lie on the same line.
100
Radius
All points on a circle are equidistant from this.
100
Quadrilateral
This is the general name for a four sides polygon
100
An acute triangle
This describes a triangle with interior angles that each measure less than 90 degrees.
100
Nonagon
This is a polygon with nine sides.
200
An angle
This geometric object is formed from two rays with a common endpoint.
200
Semicircles
Two congruent half circles with endpoints that are intersected by the diameter.
200
Parallelogram
This is a quadrilateral in which both sides of opposite sides are parallel.
200
A triangle
This is the name for a polygon with three sides
200
Octagon
This describes a polygon with eight sides.
300
non-collinear
Points J and B are NOT on the same line
300
Secant
A line that intersects the circle at two points.
300
Leg
This is the name given for either of the sides of a trapezoid that are not parallel.
300
A scalene triangle
This is a triangle that has no congruent sides.
300
Hexagon
This is a polygon with six sides

400
Base
This is the name used for either of the parallel sides of a trapezoid.
400
The hypotenuse.
Found in a right triangle, this is the side opposite the right angle.
400
Formula for calculating the total sum of interior angles in a polygon.
y=180(n-2)
500
Parallel lines
Two lines on the same plane but they do not intersect.
500
A chord
This is a segment with its endpoints on the circle
500
Opposite angles
These are interior angles of a quadrilateral with no common sides.
500
Equiangular
This describes a triangle in which all the angles are the same measure.
