Geom Essentials
This geometric figure has zero dimensions.
What is a point?
Two angles that sum to 180 degrees but are not necessarily adjacent.
What are supplementary angles?
The name of a nine-sided polygon.
What is a nonagon?
The slope of a line parallel to y = 3x + 5
What is 3?
The most common form of a linear equation
What is y=mx+b
What is slope-intercept form
This geometric figure is a part of a line that has one endpoint and goes on infinitely in one direction.
What is a ray?
Two angles that sum to 180 degrees and are also adjacent.
What is a linear pair?
The sum of interior angles of a pentagon.
What is 540 degrees?
The slope of a line perpendicular to y = 5x - 6
What is -1/5?
M=(y2-y1)/(x2-x1)
What is the slope formula?
This word describes geometric figures that lie on the same plane.
What is coplanar?
Two angles formed by intersecting lines. The angles are across from one another and are always congruent.
What are vertical angles?
The sum of the exterior angles of a decagon.
What is 360 degrees?
The trigonometric ratio of the side opposite an angle to the side adjacent to the angle.
What is the tangent?
The point in which the line crosses the y axis in a graph
What is the y-intercept?
This geometric figure is create by 2 rays with a common endpoint and measures between 90 and 180 degrees.
What is an obtuse angle?
When two parallel lines are intersected by a transversal line, name a pair of angles that is now automatically congruent. (But the lines HAVE to be parallel for this to be true.)
What are corresponding angles, alternate interior angles, or alternate exterior angles.
The formula for finding the sum of the interior angles of any polygon AND its meaning.
(n-2)180, where (n-2) is the number of triangles that make up the polygon and 180 is the sum of interior angles of each triangle.
The theorem that helps us find the distance between two points on the coordinate plane.
What is The Pythagorean Theorem?
Two lines with the same slope and a different y-intercept
What are parallel lines?
This is the intersection of a line and a plane.
What is a point?
When two parallel lines are intersected by a transversal line, name a pair of angles that is now automatically supplementary. (But the lines HAVE to be parallel for this to be true.)
What are same side interior angles or same side exterior angles?
A polygon in which at least one vertex points inward and at least one diagonal is on the polygon's exterior.
What is a concave polygon?
A line that intersects a segment at a 90 degree angle and divides the segment into two congruent segments.
What is a perpendicular bisector?
The slope of a line perpendicular to y=3/2x+2
What is -2/3?
