MATH 110 EXAMS SET EXAM PREP TESTED
QUESTIONS 2026 GRADED A+.
⫸ 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 - An angle that measures more than 90 degrees but
less than 180 degrees
⫸ Straight Angle - An angle that measures exactly 180 degrees
⫸ Vertical Angles - A pair of opposite congruent angles formed by
intersecting lines
