T
A line that cuts across two or more parallel lines.
TRANSVERSAL
If one angle formed by a transversal and parallel lines is 75 degrees, what is the measure of its corresponding angle?
75 DEGREES
If two lines are not parallel, will their corresponding angles still be congruent? Yes or No?
NO
What is the reason why a is parallel to b?
GIVEN
What do you call a line that intersects two or more other coplanar lines at two or more distinct points?
TRANSVERSAL
What is the reason why ∠1 ≅ ∠3?
CORRESPONDING ANGLES ARE CONGRUENT
A two non-adjacent angles, one interior, and one exterior on the same side of the transversal.
CORRESPONDING ANGLE POSTULATE
If a transversal intersects two parallel lines, how many pairs of congruent angles are formed?
8
What is the reason why ∠2 ≅ ∠3?
ALTERNATE INTERIOR ANGLE THEOREM
PARALLEL LINES
What do you call the angles located on opposite sides of the transversal and between the two lines.
ALTERNATE INTERIOR ANGLE THEOREM
An angles located outside the parallel lines but on opposite sides of the transversal.
ALTERNATE EXTERIOR ANGLE THEOREM
If two parallel lines are cut by a transversal, then the alternate exterior angles are ________.
CONGRUENT
These are pair of opposite angles made by two intersecting lines.
VERTICAL ANGLES
What is the sum of consecutive interior angles?
180 DEGREES
A statement that are accepted to be true without proof.
POSTULATE
TWO COLUMN PROOF
If A is congruent to B, and B is congruent to C, then A is congruent to C.
TRANSITIVE PROPERTY OF CONGRUENCE
