Lines, Points, and Planes ..oh my!
This shows an exact location
What is a Point?
A piece of line with 2 endpoints is called this
What is a Line Segment?
An angle that is exactly 90 degrees is this
What is a Right Angle?
2 angles whose measures equal 90 degrees are said to be this
What are Complementary Angles?
A line could also be called this type of angle
What is a Straight Angle?
This figure goes on forever in both directions
What is a Line?
What is 10?
Obtuse angles are angles that when measured with a protractor are this
What is Greater than 90 Degrees?
A pair of adjacent angles whose non-common sides are opposite rays are called this
What is a Linear Pair?
These types of angles are always next to each other
What are Adjacent Angles?
A flat surface that goes on forever is called this
What is a Plane?
Point B between Point A and Point C on the same line. Segment AB must be this, if Segment BC = 13 and Line AC = 20
What is 7?
Angles of this nature, when measured with a protractor equal less than 90 degrees
What are Acute Angles?
2 angles whose measures equal 180 degrees are said to be these
What are Supplementary Angles?
Given a linear pair of angles with one angle measuring 120 degrees and the other angle unknown, the unknown angle must be this
What is 60 Degrees?
Hey there, Sunshine! This has one endpoint and goes on forever in one direction
What is a Ray?
Point B between Point A and Point C on the same line. Segment BC must be this, if Line AC = 25 and Segment AB = 10
What is 15?
If 2 angles share a straight line as a common side and 1 of the angles measure 130 degrees, the adjacent angle must measure this
What is 50 Degrees?
These 2 angles ALWAYS equal each other...they are opposite each other
What are Vertical Angles?
One angle of a vertical pair is 63 degrees. The other angle is labeled 7n. The variable "n" must equal this
What is 9?
Points on the same line can be called this
What is Collinear?
The rule that states the following (if points A, B, and C are all on the same line with B between A and C): AC = AB + BC is called this
What is the Segment Addition Postulate?
If a ray divides an angle, the measure of the whole angle is the sum of the measures of the two smaller angles created...which is know as this
What is the Angle Addition Postulate?
One angle of a vertical pair of angles equals 23, which means the other angle equals this
What is 23?
X must equal this, if looking at 2 complementary angles with one measuring 45 and the other measuring X + 15
What is 30?
