Notation
This is notated by a single capital letter. (Ex: P)
What is a point?
The theorem that states that two angles opposite each other produced by 2 intersecting straight lines are congruent
What is the vertical angles theorem?
the space in formed when 2 lines intersect, usually measured in degrees
What is an Angle?
Two angles with congruent measures.
What are congruent angles?
Angles that share a common vertex and side.
What is an adjacent angle?
This is notated by ∠ and then the identifying letters.
What is an angle?
The postulate that states that if two angles form a linear pair they are supplementary
What is the linear pair postulate?
a pair of opposite congruent angles
What is a Vertical Angle?
The point where two lines intersect
What is a vertex?
A line that ends at one point and extends infinitely in the other direction.
What is a ray?
This is notated by 2 capital letters with a single straight line over them.
What is a line segment?
This Postulate means the measure of an angle made by two angles side by side is the total measure of the two angles
What is the Angle Addition Postulate?
2 shapes that share a common side and vertices that do not overlap
What does it mean to be Adjacent?
A specific spot in the universe.
What is a point?
If angle ∠1 is adjacent to ∠2 and ∠1=35o and ∠2=68o and ∠3 is the accumulation of ∠1 and ∠2 then what is the value of ∠3?
What is 103o?
This is notated by 2 straight lines in between 2 line segments. (Ex: AB||BC)
What is parallel lines?
The theorem that states that if 2 angles are complementary to the same angle, then they are congruent
What is the Congruent Complements Theorem?
2 angles whose measures add up to 90o
What are complementary angles?
Two points that are of the same line
What is colinear?
One vertical angle has a measure of 45o. What is the measure of the other angle?
What is 45%?
This is notated by this ⊥ symbol inbetween 2 line segments. (Ex: AB⊥BC)
What are perpendicular lines?
The theorem that states that if 2 angles are supplementary to the same angle, then they are congruent
What is the congruent supplements theorem?
2 angles whose measures add up to 180o
What are supplementary angles?
2 angles whose measures add up to 180
What is a linear pair?
A linear pair has an one angle with a measure of 118o. What is the measure of the other angle?
What is 62o?
