The line that intersects two or more coplanar lines in different points transversal
Two lines that meet and form right angles perpendicular lines
A 90 degree angle is called a right angle
An angle less than 90 degrees acute angle
An angle more than 90 degrees but less than 180 degrees obtuse angle
The common end point of an angle vertex
A ray in the interior of an angle that divides the angle into two angles of equal measure bisector of an angle
Minutes in one degree 60
Seconds in one minute 60
Seconds in one degree 3600
Two angles in the same plane, have a common vertex and common side, but no interior points in common adjacent angles
Two angles with measures that together total 90 degrees complementary angles
Two angles with measures that together total 180 degrees supplementary degrees
Equal angles with sides that form two pairs of opposite rays vertical angles
When two lines are cut by a transversal, how many angles are formed? 8
The equal angles between parallel lines, cut by a transversal, each on alternate sides of the transversal alternate interior angles
The equal angles outside of the parallel lines cut by a transversal, each on opposite sides of the transversal alternate exterior angles
The equal angles, one outside of the parallel lines cut by the transversal, one inside the parallel lines cut by the transversal, and both on the same side of the transversal corresponding angles
Two supplementary angles inside the parallel lines cut by a transversal, both on the same side as the transversal Same side interior angles
Interior Angles on the Same Side of the Transversal are AKA IASST
Alternate Interior Angles are AKA AIA
Alternate Exterior Angles are AKA AEA
Vertical angles are AKA VA
A triangle in which ALL angles are EQUAL Equiangular Triangle
A triangle in which ONE angle is a RIGHT angle Right Triangle
A triangle in which ONE angle is OBTUSE Obtuse Triangle
A triangle in which ALL THREE angles are ACUTE Acute triangle
A triangle in which NO TWO SIDES have the same length Scalene Triangle
A Triangle in which AT LEAST TWO SIDES have the same length Isosceles Triangle
A triangle in which ALL THREE SIDES have the same length Equilateral Triangle
Two interior angles of a triangle not adjacent to the exterior angle remote interior angles
An angle formed by one side of a triangle and an extension of another side exterior angle of a triangle
The sum of the interior angles of a triangle 180 degrees
The measure of this angle of a triangle is equal to the sum of the measures of the remote interior angles and also supplementary to the adjacent interior angle exterior angle
Any closed figure bounded by three or more segments that only intersect at their end points. polygon
How many sides does a hexagon have? 6
A polygon with eight sides octagon
A polygon with five sides pentagon
A polygon with n sides n-gon
What is the formula for finding the number of diagonals from one vertex of an n-gon? n-3
What is the formula for finding the number of triangles in an n-gon? n-2

What is the formula for the sum of angles in an n-gon? (n-2)180 degrees
What is the formula for finding ONE interior angle of an n-gon (n-2)180 degrees divided by n
What is the formula for finding the number of sides in an n-gon (n-2) 180 degrees divided by the measure of one interior angle
Whatever number of sides of a polygon, the exterior angles ALWAYS total 360 degrees
If the exterior sides of two adjacent angles are in perpendicular lines, the angles are complementary
A line placed in a figure to make a proof possible auxiliary line
Two lines that do not lie in the same plane skew lines
Lines that are in the same plane and have NO points in common parallel lines
