A triangle with three unequal sides and unequal angles.
What is a scalene triangle?
100
The number that is determined by the ratio of the circumference and the diameter. More specifically, circumference divide by diameter.
What is pi?
100
An eight sided polygon.
What is an octagon?
200
The figure that begins at a point and extends infinitely in one direction.
What is a ray?
200
A triangle that is equiangular.
What is an equilateral triangle?
200
The angle formed by two radii of a circle.
What is the central angle?
200
A nine sided polygon.
What is a nonagon?
300
The figure created by two rays that meet at a common endpoint, provided the rays are not collinear.
What is an angle?
300
A line segment that connects a vertex of a triangle to the midpoint of the opposite side
What is a median?
300
The line segment where both endpoints lie on the circle.
What is a chord?
300
The interior angle measure of a regular pentagon.
What is 108°?
400
Adjacent angles whose non common side form a line.
What is a linear pair?
400
What point is equidistant from all three vertices of a triangle. This point is also constructed by finding the point of concurrency of the three perpendicular bisectors of the triangle.
What is the circumcenter?
400
The exterior angle measure of hexagon?
What is 60°?
500
The set of all points that are equidistant from a single point.
What is a circle?
500
The point that is equidistant from each side of a triangle. This point of concurrency is found by the intersection of the three angle bisectors of the triangle.
What is the incenter?
500
The general formula to find the interior angle measure of any polygon.
What is (180 * (n - 2))/n, where n represents the number of sides of the polygon.
