What else can I help you with?
What else would need to be congruent to show abc is congruent to xyz by SAS given ab congruent xy and bc congruent yz?
To show that triangle ABC is congruent to triangle XYZ by the Side-Angle-Side (SAS) criterion, we also need to establish that the included angles are congruent. Specifically, we need to demonstrate that angle ABC is congruent to angle XYZ. With the two pairs of congruent sides (AB ≅ XY and BC ≅ YZ) and the included angle congruence, SAS can be satisfied.
What is the angle-angle-side rule?
Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.
What is the difference between angle side angle and angle angle side?
The first is two angles and the included side whereas the second is two sides and the included angle!
What postulate states that two triangles are congruent if two sides and an included angle are congruent?
The SAS (Side-Angle-Side) postulate.
If we know that two sets of corresponding angles and the corresponding included sides are congruent in two triangles what can we say about the triangles?
If two sets of corresponding angles and the corresponding included sides are congruent in two triangles, we can conclude that the triangles are congruent by the Angle-Side-Angle (ASA) postulate. This postulate states that if two angles and the included side of one triangle are respectively equal to two angles and the included side of another triangle, then the two triangles are congruent. Therefore, the triangles have the same shape and size.
What are three ways that you can prove that triangles are congruent?
If triangles have the corresponding sides congruent then they are congruent. SSS If two triangles have two sides and an included angle congruent then they are congruent. SAS If two triangles have two angles and an included side congruent then they are congruent. ASA SSA doesn't work.
What must be shown to be congruent in order to say that the triangles are congruent by SAS?
Two sides and the included angle of one triangle must be congruent to two sides and the included angle of the other.
What is Angle Side Angle?
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
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 This is known as what?
SAS
What is Side Angle Side?
If two sides and the included angle of one of one of the triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
What is the SAS postulate?
The SAS Postulate states if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

What does a triangle need to have to be congruent?
A single triangle is never congruent. "Congruent" only arises out of a comparison with something else. In order to be congruent to another triangle, a triangle needs one of the following: -- two of its sides and the included angle equal respectively to two sides and the included angle of the other one; -- two of its angles and the included side equal respectively to two angles and the included side of the other one; -- all three of its sides equal respectively to all three sides of the other one.
