Question

56 what does the \included angle\ mean in triangle congruence?
a. the angle formed by the two given sides
b. the largest angle in the triangle
c. the smallest angle in the triangle
d. the angle opposite the given sides

Explanation:

In triangle congruence, the "included angle" is defined as the angle formed by two given sides (the two sides that are part of the congruence criteria, like in SAS - Side - Angle - Side congruence). Option a says "The angle formed by the two given sides" which matches this definition. Option b is incorrect as included angle isn't about being the largest. Option c is incorrect as it's not about being the smallest. Option d is incorrect as it's not about opposite sides.

Answer:

a. The angle formed by the two given sides
