Wording For Proofs Flashcards
If segments congruent,
then segments = in length
If segments = in length,
then segments congruent
If midpoint,
then segment divided into 2 congruent segments
If segment divided into 2 congruent segments,
then midpoint
If (segment, ray, line) bisects segment,
then segment divided into 2 congruent segments
If segment divided into 2 congruent segments,
then (segment, ray, line) bisects segment
If angle bisected,
then angle divided into 2 congruent angles
If angle divided into 2 congruent angles,
then bisected
If right angle,
then 90 degrees
If 90 degrees,
then right angle
If straight angle,
then 180 degrees
If 180 degrees,
then straight angle
If angles congruent,
then angles equal in measure
If angles equal in measure,
then angles congruent
If 2 angles supp,
then their sum = 180 degrees
If 2 angles sum = 180 degrees,
then 2 angles supp
If 2 angles comp,
then their sum = 90 degrees
If 2 angles sum = 90 degrees,
then 2 angles comp
If perpendicular lines,
then right angles
If right angles,
then perpendicular lines
If right triangle,
then right angle
If triangles congruent
then all corres parts are congruent
If all corres parts of triangles are congruent,
then triangles congruent
If 2 angles are sup to the same angle (or to congruent angles),
then they are congruent
If angles are comp to the same angle (or to congruent angles),
then they are congruent
Vertical angles are congruent
Theorem
All right angles are congruent
Theorem
If 2 parallel lines,
then alt int angles are congruent
If 2 parallel lines,
then alt ext angles are congruent
If 2 parallel lines,
then consecutive int angles are supp
If alt int angles are congruent,
then 2 parallel lines
If alt ext angles are congruent,
then 2 parallel lines
If consecutive int angles are sup,
then 2 parallel lines
Sum of angles in a triangle = 180 degrees
