It has no dimension and is represented by a dot.
What is a point
|
Opposite rays are 2 rays that have the same endpoint and are collinear
What are opposite rays
|
If P is in the interior of angle RST then the measure of angle RST is equal to the sum of the measures of angle RSP and angle PST
What is the Angle Addition Postulate
|
Reflexive-For any segment AB=AB
Symmetric-If CD=AB then AB=CD Transitive-If AB=CD and CD=EF then AB=EF
What is the congruence of segments theorem
|
angle 1 is equal to 120 degrees because in the vertical angle congruence theorem it sates that vertical angles are congruent
If angles 1 and 2 are vertical angles and 2=120 degrees then what is the degree of angle 1
|
A line has 1 dimension It is represented by a line with 2 arrowheads but it extends without an end.
What is a line
|
A midpoint is a point that cuts a segment into 2 equal parts.
What is a midpoint
|
If B is between A and C the AB+BC=AC
What is the segment addition postulate
|
|
The degree of angle 1 is 80 degrees because if they are a linear pair they are supplementary and they add up to 180 degrees
If 1 and 2 are a linear pair and the degree of angle 2 is 100 degrees what is the degree of angle 1
|
A plane has 2 dimensions it is represented by a shape that looks like a floor or a wall but it extends without an end.
What is a plane
|
The 2 angles that are below 91 degrees are an acute angle which is from 1-89 degrees and a right angle which is 90 degrees
What are the 2 angles that are less than 91 degrees
|
1-Through any 2 points there is 1 plane
2-A line has at least 2 points 3-the intersection of 2 lines is 1 point 4-through 3 noncollinear points there is 1 plane 5-A plane contains 3 noncollinear points 6-If 2 points lie in a plane then the line containing them lies in the plane 7-The intersection of 2 planes is a line
What are the point line and plane postulates
|
All right angles are congruent
What is the right angles congruence theorem
|
It would be 60 degrees because consecutive interior angles are supplementary
If angles 1 and 2 are consecutive interior angles and 2=120 degrees then what is the degree of angle 1
|
A segment is part of a line with 2 endpoints and is represented by the 2 endpoints and a segment above.
What is a segment
|
The 2 angles that are higher than 90 degrees are an obtuse angle which is 91-179 degrees and a straight angle which is 180 degrees
What are the 2 angles that are more the 90 degrees
|
If 2 angles form a linear pair then they are supplementary
What is the linear pair postulate
|
If 2 angles are supplementary to the same angle or congruent angles then they are congruent
What is the Congruent Supplements Theorem
|
It would be 120 degrees because corresponding angles are congruent
If angles 1 and 2 are corresponding angles and 2=120 degrees then what is the degree of angle 1
|
A ray is part of a line with 1 endpoints and one other point and is represented by the 1 of the endpoints and one other point and a ray above.
What is a ray
|
An angle bisector is a ray that cuts an angle into 2 equal parts
What is an angle bisector
|
Vertical angles are congruent
What is the Vertical Angles Congruence Theorem
|
If 2 angles are complementary to the same angle or to congruent angles then they are congruent
What is the congruent complements theorem
|
It would be 120 degrees because alternate exterior angles are congruent
If angles 1 and 2 are Alternate exterior angles and 2=120 degrees then what is the degree of angle 1
