point lines and planes and segments
What represents a point
A dot
what is a conjecture
a conclusion reached by using inductive reasoning. A conjecture is not certain, it only can be likely true.
what are parallel line
lines that don't intersect and goes on forever
whar is a midsegmenty
a segment connecting the midpoints of two sides of a triangle.
What do you call a 90 degree angle
complementary
What is it called when a line has two arrowheads that extend without ending
A line
allows us to reach a conclusion based on the pattern of the given information.
Inductive reasoning
What are skew lines
two lines that do not intersect. They are not on the same plane
If a point is on the perpendicular bisector of a segment it is?
equidistant
What is law of detachment
if you are given a true conditional, p ⇒ q, and the hypothesis, p, occurs, then the conclusion, q, is true.
what are point called that lie on the same PLANE
coplanar
what is the hypothesis of this conditional statement
If an animal is a cat, then it is a mammal
an animal is a cat
what is the notation for parallel lines
||
What is a perpendicular bisector
a line that intersects another line segment at a 90-degree angle
what is a median
a segment whose endpoints are a vertex and the midpoint of the opposite side.
what is points called that lie on the same LINE
collinear point
fine the converse and inverse of this statement
If figure is a triangle, then it has 3 sides
converse:If a figure has 3 sides, then it is a triangle
inverse:If figure is not a triangle, then it does not have 3 sides.
Angles that are non-adjacent interior angles that lie on opposite sides of the transversal are?
Alternate Interior Angles
what is conrruent
occurring or existing at the same time.
proportion is
equation that states that two ratios are equivalent.
A point, line, ray, or other segment that intersects a segment at its midpoint is the
segment bisector
what is the countarpositive of this conditional statement
If figure is a triangle, then it has 3 sides.
If a figure does not have 3 sides, then it is not a triangle.
Transversal is when?
A line that intersects two or more coplanar lines at a distinct point
If a point is equidistant from the endpoints of a segment its a
perpendicular bisector
If I simplify 18:12 what will I get
3:2
