Question 486577
The third angle will be 90 degrees, as the three will add to 180 degrees.
A This will not necessarily be a congruent triangle. The angles are congruent, so the triangles are similar.
B. An angle of 90 degrees is congruent to the corresponding 90 degree angle.
C. The sides would be similar but not congruent.
D. Those parts would be congruent, but not necessarily the triangles.
E. Yes, and by the SAS theorem, the two triangles will be congruent.
F. No, for the SAS theorem you need the two sides and the included angle, the 60 degree angle will not be the included angle.
Cleomenius.
