coplaner angle that have a common vertex and one common side, but no common interior points-
two non-adjacent angles formed by two intersecting lines-
two adjacent angles whose non-common sides are two rays going in opposite directions- X
sum of the measures of the two angles is 90 degrees-CO = 90
sum of the measures of the two angles is 180 degrees- super!
non coplaner lines that never intersect
portion of a line w/ 2 endpoints
a line w/ a never ending point
lines that intersect to form right angles
points that are not all on the same line
points aren't on the same plane
coplanar lines that never intersect
a set of points or lines all lying on the same plane
a set of points all lying on the same line
Postulate is a true statement, which does not require to be proved.
an exact position or location on a plane surface
A geometrical object that is straight, infinitely long and infinitely thin.
flat surface that is infinitely large and with zero thickness
A general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.
is a line or a ray or a segment that divides a line segment into two equal parts.
A line or ray that divides an angle in half.
a line is the point at which the line crosses the y axis.
The rate of change of a line
a logical relationship between two propositions, or statements. For
An example that refutes or disproves a hypothesis, proposition, or theorem.
slop intercept form
A logical statement involving a comparison, which yields a Boolean (True or False) value..
an if-then statement in which the hypothesis and the conclusion are switched.
formed by negating the hypothesis and negating the conclusion of the original statement.
center of dilation
In a dilation, the fixed point about which the figure is enlarged or reduced. It's also the intersection point of the lines that extend through the corresponding vertices of the original and dilated image.
the figure before the transformation is applied
the figure after the transformation is applied, indicated by primes - A'B'C'
the ratio used to enlarge or reduce similar figures
figures that are the same size and same shape - angles and side lengths are all congruent
figures that are the same shape but different size - angles are congruent and sides are proportional
transformations in which the pre-image and image are congruent figures: rotations, translations, reflections
