Answer:
Several amendments were added to the Constitution to recognize suffrage rights of certain groups. Ratified in 1870, the 15th Amendment recognized the voting rights of African American men. Fifty years later, Congress and the states ratified the 19th Amendment. This amendment recognized the suffrage rights of women.
Step-by-step explanation:
3 difference's are different laws for the opposite gender(male female)
one is about voting rights for the African American men
then the last one is when they did it they were 50 years apart(yes i know that that one sounds a little silly but it is a difference)
one was for the men the 15 the woman 19 they were both different laws
3 similarities are that they are both are amendments
that they are doing good things for both the men and woman(yea it's pretty obvious but i ran outta one and it is not incorrect either and technically it is correct)
and finally they both were able to vote (the men and woman)
