100

A midpoint creates two congruent segments (sides)

Definition of Midpoint

100

Two angles and a non-included side are congruent

AAS

100

Straight lines form how many degrees?

180 degrees

100

200

A side is being shared, so the side is congruent to itself.

Reflexive Property

200
Two sides and the included angle are congruent

300

The opposite angles formed by 2 intersecting lines are congruent.

Vertical Angles

300
