10. under what circumstances are two non
right triangles congruent?

Two non right triangles would be considered congruent if it would follow at least one of the congruence theorems. They would be congruent if it follows the:
- SSS (side - side - side) theorem where all of the corresponding sides are equal in measurement.
- SAS (side - angle - side) theorem where one pair of a corresponding side and an included angle are of equal values.
-ASA (angle - side - angle) theorem where two pairs of corresponding angle and an included side length are equal.
-AAS (angle - angle - side) theorem where one pair of corresponding angle and non-included side are the same values.
-AAA where all of the angles are of the same value.
