answers 2025
Triangle
Polygon
A closed plane figure made up of line segments
Line
is straight (no curves), • has no thickness, and. • extends in both directions without end
(infinitely).
Ray
A part of a line, with one endpoint, that continues without end in one direction
Endpoint
A point at either end of a line segment, or a point at one end of a ray.
Vertex of a Polygon
The intersection of two sides of the polygon
Diagonal
A straight line connecting any two vertices of a polygon that are not adjacent
Parallel Sides
Lines or segments that are the same distance apart and never touch.
Congruent Sides
Sides that have the same length
Adjacent Sides
, In a polygon, two sides that intersect to form a vertex.
Opposite Sides
Two sides that do not share a vertex
Center of a Polygon
The center of a polygon's circumscribed circle
Central Angle of a Polygon
An angle formed by two radii drawn to consecutive vertices of the polygon
Vertex Angle of a Polygon
An angle formed by three consecutive vertices
Equilateral
All sides are congruent
Equiangular
All angles are congruent
Regular Polygon
A polygon that is both equilateral and quadrangular
Right Angle
90 degree angle
Acute Angle
An angle that measures less than 90 degrees
Obtuse Angle
