Tranversal (131)
|
a line that intersects 2 or more coplanar lines at different points.
|
|
|
Corresponding Angles (131)
|
Two angles that occupy corresponding positions.
|
|
|
Alternate Exterior Angles (131)
|
Two angles that lie outside the two lines on opposite sides of the transversal.
|
|
|
Alternate Interior Angles (131)
|
Two angles that lie between the two lines on opposite sides of the transversal.
|
|
|
Consecutive Interior Angles (131)
|
Two angles that lie between the two lines on the same side of the transversal.
aka Same Side Interior Angles |

|
Postulate 13: Parallel Postulate (130)
|
If there is a line and a point not on the line, then there is exactly one line through the point parallel to the given line.
|
|
|
Postulate 14: Perpendicular Postulate
|
If there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line.
|
|
|
Theorem 3.1
|
If two lines intersect to form a linear pair of congruent angles, then the line are perpendicular.
|
|
|
Theorem 3.2
|
If two sides of two adjacent acute angels are perpendicular, the the angles are complementary.
|
|
|
Theorem 3.3
|
If two lines are perpendicular, then they intersect to form four right angles.
|
|
|
Postulate 15: Cooresponding Angles Postulate
|
If two parallel lines are cut by a transversal, then the two pairs of corresponding angles are congruent.
|
|
|
Theorem 3.4: Alternate Interior Angles
|
If tow parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
|
|
|
Theorem 3.5: Consecutive Interior Angles
|
If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary.
|
|
|
Theorem 3.6: Alternate Exterior Angles
|
If two parallel lines are cut by a transversal,then the pairs of alternate exterior angles are congruent.
|
|
|
Theorem 3.7: Perpendicular Transversal
|
If two parallel lines are cut by a transversal, then it is perpendicular to the other.
