They are arcs of congruent circles.
what is the congruent diagonals each of which divides the figure into two congruent isosceles right triangles
If they're in the same circle or in circles of equal radii (radiuses), then yes.
A bisector.
No. Consider two circles of diameter 10cm and 20cm respectively. For the smaller circle consider the arc formed by half the circle. It has a length of pi*5 (where * means multiply) For the larger circle, consider the arc formed by a quarter of the circle. It has a length of pi*5. Both arc lengths are the same but they are not congruent. They have entirely different shapes.
In the same circle, or in congruent circles, two minor arcs are congruent if and only if their corresponding chords are congruent.
same circle or congruent circles
The answer is false
Parallel lines intercept congruent arcs on a circle. More explanation: Parallel lines never interSECT but they can interCEPT Congruent arcs means that the two arcs would have the same measure of the arcs.
They are arcs of congruent circles.
they must be in the same circle or congruent circles they must have the same central angle measure
Congruent circles, maybe...
A midpoint is a point that divides a segment into two congruent segments. A angle bisector is a ray that divides an angle into two congruent angles.
Only if they belong to congruent circles.
what is the congruent diagonals each of which divides the figure into two congruent isosceles right triangles
If they're in the same circle or in circles of equal radii (radiuses), then yes.
The diagonal of a parallelogram divides it into two congruent triangles. This is because the diagonal creates two pairs of congruent triangles by dividing the parallelogram into two equal halves.
