You need only know the radius of each circle to determine that they are congruent. If the radii are identical, the circles are identical. This can also be determined by comparing the diameters (twice the radii), or the circumferences, or the areas of the circles. In all cases, if the parameters are identical, the circles are identical.
No, because they need not be congruent.
The answer depends on what is already known about the two triangles.
Because Corresponding Parts of Congruent Triangles, there are five ways to prove that two triangles are congruent. Show that all sides are congruent. (SSS) Show that two sides and their common angle are congruent. (SAS) Show that two angles and their common side are congruent. (ASA) Show that two angles and one of the non common sides are congruent. (AAS) Show that the hypotenuse and one leg of a right triangle are congruent. (HL)
sss
"What else" implies there is already something that is congruent. But since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer. no correct
We don't know what has already been proven congruent, sowe're in no position to be able to say what elseis required.
For a start, you would need to know what efg and jkl are.
SSS is enough to show congruence.
No, because they need not be congruent.
__ - __ AC = XZ = is the similar sign
Angle "A" is congruent to Angle "D"
The answer depends on what is already known about the two triangles.
Line segment BC is congruent to Line Segment YZ
That depends on which sides have not been proven congruent yet.
