Which type of triangle will always have exactly 1-fold reflectional symmetry?

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
