Prove Triangles Congruent by ASA and AAS: �Angle-Side-Angle (ASA) Congruence Postulate:

Prove Triangles Congruent by ASA and AAS: �Angle-Side-Angle (ASA) Congruence Postulate: �If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent.

Prove Triangles Congruent by ASA and AAS: �Angle-Side-Angle (ASA) Congruence Postulate: �If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent. �In other words:

Prove Triangles Congruent by ASA and AAS: �Angle-Side-Angle (ASA) Congruence Postulate: �If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent. �In other words: � If the side in between two angles that are the same is the same, the triangles are the same.

Prove Triangles Congruent by ASA and AAS: �Angle-Side (AAS) Congruence Postulate:

Prove Triangles Congruent by ASA and AAS: �Angle-Side (AAS) Congruence Postulate: �If two angles and a non-included side of one triangle are congruent to two angles and the corresponding nonincluded side of a second triangle, then the two triangles are congruent.

Prove Triangles Congruent by ASA and AAS: �Angle-Side (AAS) Congruence Postulate: �If two angles and a non-included side of one triangle are congruent to two angles and the corresponding nonincluded side of a second triangle, then the two triangles are congruent. �In other words:

Prove Triangles Congruent by ASA and AAS: �Angle-Side (AAS) Congruence Postulate: �If two angles and a non-included side of one triangle are congruent to two angles and the corresponding nonincluded side of a second triangle, then the two triangles are congruent. �In other words: � If two angles are the same, and a side not in between the angles are the same, the triangles are the same.

Using a flow proof:

Using a flow proof: A flow proof uses arrows to show the flow of a logical argument. Each reason is written below the statement it justifies.

Use a flow proof to solve: �In the diagram, CE BD and CAB = CAD. Prove ABE = ADE.

Are the triangles congruent? How do you know?
