triangle congruence theorems
sas

1. the a in sas means

only one
angle in the
triangle
that you
need two
sides and any
angle
side and side
the two sides
make up the
corresponding
angle

Explanation:

To determine the meaning of the "A" in SAS (Side - Angle - Side) for triangle congruence:

• Option 1: SAS requires a specific angle (the included angle), not "only one angle" in a general sense. Eliminate this.
• Option 2: SAS needs the angle between the two sides (included angle), not "any angle". Eliminate this.
• Option 3: "side AND side" does not relate to the meaning of "A" (angle). Eliminate this.
• Option 4: In SAS, the two sides form (are the sides of) the corresponding included angle. This matches the definition of SAS (two sides and the included angle between them).

Answer:

The option "The two sides make up the corresponding angle" (the last option among the given choices).
