Terms in Geometry
It is an undefined term in geometry that represents an exact location in space and has no size, length, or width.
Point
Two pair of angles whose measure have a sum of 900.
Complementary Angles
It is a line that intersects two or more lines at distinct points.
Transversal Line
The figure formed by two rays with a common endpoint is called an __________________.
Angle
If one angle measures 35°, what is the measure of its complementary angle?
55o
It is an undefined term that extends infinitely in two opposite directions and is made up of infinitely many points.
Line
Two pair of angles whose measure have a sum of 180o.
Supplementary Angle
A transversal intersects two parallel lines. Angles that are in the same relative position are called:
Corresponding angles
The common endpoint of two rays that form an angle is called the __________________.
Vertex
If two angles form a linear pair and one angle measures 120°, what is the measure of the other angle?
60o
It is a flat surface that extends infinitely in all directions.
Plane
When two angles share a common vertex and side but do not overlap, which term best describes their relationship?
Adjacent angles
When two parallel lines are cut by a transversal, which angles are found inside the lines but on opposite sides of the transversal?
Alternate interior angles
An angle that measures less than 90o is called?
Acute Angle
If two vertical angles are formed and one angle measures 48°, what is the measure of the opposite angle?
48°
It is a part of a line that has one endpoint and extends infinitely in one direction.
Ray
In a diagram where two lines intersect, the opposite angles formed are always equal. What are these angles called?
Vertical Angles
Angles that lie outside two parallel lines and on opposite sides of a transversal are called:
Alternate exterior angles
An angle that measures exactly 90o is called?
Right Angle
A transversal cuts two parallel lines forming corresponding angles. If one angle is 75°, what is the corresponding angle?
75o
Two or more points that lie on the same line is called?
Collinear Points
A pair of adjacent angles formed when two straight lines intersect.
Linear Pair
If two angles lie on the same side of a transversal and between two parallel lines, they are:
Same side interior angles
An angle that measures exactly 360o is called?
Full Angle
Angle PQR is a right angle. Ray QS divides the angle forming ∠PQS = 41°. What is the measure of ∠SQR?
49o
