If the sides AB, BC and CA of triangle ABC correspond to the sides DE, EF and FD of triangle DEF, then the two triangles are congruent if:
- AB = DE, BC = EF and CA = FD (SSS)
- AB = DE, BC = EF and angle ABC = angle DEF (SAS)
- AB = DE, angle ABC = angle DEF, angle BCA = angle EFD (ASA)
If the triangles are right angled at A and D so that BC and EF are hypotenuses, then the triangles are congruent if
- BC = EF and AB = DE (RHS)
- BC = EF and angle ABC = angle DEF (RHA).

What are congruence theorems?
there are 4 types of congruence theorem-: ASA,SSS,RHS,SAS
What are the properties of geometry?
logic postulates theorems
Can postulates be used to solve theorems?
No. A postulate need not be true.
What are the postulates and theorems?
Postulates are statements that are assumed to be true without proof. Theorums are statements that can be deduced and proved from definitions, postulates, and previously proved theorums.
What do you use as reasons to support the steps of geometric proof?
the theorems and postulates used in the proof
Wwhich of the following are not congruence theorems or postulates?
the congruence theorems or postulates are: SAS AAS SSS ASA
What are the congruence theorems or postulates?
They are theorems that specify the conditions that must be met for two triangles to be congruent.
Are not congruence theorems or postulates?
Putting a question mark at the end of a few words does not make it a sensible question. Please try again.

logic postulates theorems
How the triangle similarity postulates are alike and how they differ from triangle congruence postulates?
Similarity is where triangles have equal angles at each corner. Congruence is where triangles have sides of equal length.
What is always true in a logical system?
Theorems, corollaries, and postulates.
