Segment and Angle Proof

In a triangle what is the line segment drawn from a vertex perpendicular to the opposite side (or an extension of the opposite side?

• Median of a Triangle

• Altitude of a Triangle

• Perpendicular Bisector of a side of a Triangle

• Angle Bisector

• Midpoint of a Line Segment

What is a line segment or ray drawn from a vertex that divides the angle into two congruent angles?

• Median of a Triangle

• Altitude of a Triangle

• Perpendicular Bisector of a side of a Triangle

• Angle Bisector

• Midpoint of a Line Segment

When two parallel lines are cut by a transversal, then: (select all that apply)

• Vertical angles are congruent.

• The exterior angle is equal to the sum of the two remote interior angles

• Corresponding angles are congruent

• Alternate interior angles are congruent

• Same-side interior angles are congruent
