Congruent Triangles - Vertical Angles and Reflexive Prop

Front

What is the Reflexive Property in geometry?

Back

The Reflexive Property states that any geometric figure is congruent to itself. For example, triangle ABC is congruent to triangle ABC.

What are Vertical Angles?

Back

Vertical Angles are the angles opposite each other when two lines intersect. They are always congruent.

How can you determine if two triangles are congruent using the Reflexive Property?

Back

If two triangles share a side, that side can be used to show that the triangles are congruent by the Reflexive Property.

What is the significance of Vertical Angles in proving triangle congruence?

Back

Vertical Angles can be used to establish that two angles in different triangles are equal, which can help in proving the triangles are congruent.

Can two triangles be congruent without using the Reflexive Property or Vertical Angles?

Back

Yes, triangles can be congruent through other methods such as Side-Angle-Side (SAS) or Angle-Side-Angle (ASA) congruence.

What is an example of a situation where neither the Reflexive Property nor Vertical Angles apply?

Back

If two triangles do not share any sides or angles, and there is no information about their angles or sides, neither property can be used.
