Miscellaneous Flashcards
2 adjacent(next to) angles that are supplementary(their measures add up to 180 degrees).
Linear pair
2 angles that share the same side and vertex
Adjacent angles
2 angles anywhere on a plane(they don’t have to be adjacent)whose measures add up to 180 degrees.
Supplementary angles
2 angles anywhere on a plane(they don’t have to be adjacent)whose measures add up to 90 degrees.
Complementary angles
If you are given two points, then ________
There is exactly one line connecting them.
Through any three noncollinear points, _________
There is exactly one plane containing them.
If two points lie in a plane, then _____
the line containing those points lies in that same plane.
If two unique lines intersect, then _____
They intersect in exactly one point.
If two planes intersect, then _________
They intersect in exactly one line.
Every number or measure equals itself.
a = a
Reflexive Property
Similar to a chain of events leading to one final statement that ties the previous statements together.
If a=b and b=c, then a=c.
Transitive Property
Simplifying an equation/expression into a different thing that is still equal.
a+1+2 = a + 3
Substitution
The property stating that you are able to switch the expressions in an equation to opposite sides of the equals sign.
a=c
c=a
Symmetric property
The property that states if you add/subtract/multiply/divide on both sides of the equation, then it will still be equal.
a=a
a+1=a+1
Addition/Subtraction/Multiplication/Division Property of equality
Two intersecting angles whose non-adjacent angles have the same measure.
Vertical Angles
