See explanation
Step-by-step explanation:
The triangles below are congruent and their corresponding parts are marked.
a) Angles marked with one arc are congruent, so 
Angles marked with two arcs are congruent, so 
Angles marked with three arcs are congruent, so 
b) Sides marked with one segment are congruent, so 
Sides marked with two segments are congruent, so 
Sides marked with three segments are congruent, so 
c) Name teo congruent triangle following the congruence of angles:

8X5000 is 40000. There's three zeroes in5000 and no zeroes in 8, yet there are 4 zeroes in the answer. This is because you must multiply the non-zeroes, and then add the zeroes from your factors. 8 times 5 is 40, add 3 zeroes to get 40000.
