Similarity and Congruence
100
This geometric figure has zero dimensions.
What is a point?
100
Two angles that sum to 180 degrees but are not necessarily adjacent.
What are supplementary angles?
100
The name of a nine-sided polygon.
What is a nonagon?
100
The slope of a line parallel to y = 3x + 5
What is 3?
100
2 triangles are similar when these parts of the triangles are congruent
What are the angles?
200
This geometric figure is a part of a line that has one endpoint and goes on infinitely in one direction.
What is a ray?
200
Two angles that sum to 180 degrees and are also adjacent.
What is a linear pair?
200
The sum of interior angles of a pentagon.
What is 540 degrees?
200
The slope of a line perpendicular to y = 5x - 6
What is -1/5?
200
This is the first method to solving proportions in the form a/b = c/d
What is cross multiply?
300
This word describes geometric figures that lie on the same plane.
What is coplanar?
300
Two angles formed by intersecting lines. The angles are across from one another and are always congruent.
What are vertical angles?
300
The sum of the exterior angles of a decagon.
What is 360 degrees?
300
The trigonometric ratio of the side opposite an angle to the side adjacent to the angle.
What is the tangent?
300
You can use this method to prove 2 triangles are congruent. It involves showing 2 sides and the angle in between are congruent.
What is Side Angle Side (SAS)?
400
This geometric figure is create by 2 rays with a common endpoint and measures between 90 and 180 degrees.
What is an obtuse angle?
400
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.
400
A polygon in which all vertices point outward and all diagonals are on the polygon's interior.
What is a convex polygon?
400
The theorem that helps us find the length/distance of the sides of right triangles.
What is The Pythagorean Theorem?
400
This is the definition of similar figures.
What is "figures that have all angles congruent and all sides proportional?"
500
This is the intersection of a line and a plane.
What is a point?
500
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?
500
This is the Formula you use when trying to find the missing angle of any triangle when all side lengths are known.
What is the Law of Cosines?
500
A line that intersects a segment at a 90 degree angle and divides the segment into two congruent segments.
What is a perpendicular bisector?
500
Using this image, this is the measurement of segment AB when BD=2.
What is the (√2)?
