Geometry

I need help with counterexamples and all the questions are false.
1.If an angle measures 34 degrees ,then the angle is acute.
2.If the length of twwo segments are each 17 feet,then the segments are congruent.
3.If two angles 32 and 148 degrees ,then are supplementary.
4.If you chose number 13,then you chose a prime number.

I found that they are false.I just need help proving it.
