How to do error handling where it will only be possible to insert numbers?

Question

import math

print('Insira comprimento do Lado \"C\":')

lado_c = float(input())

print('Insira comprimento do Lado \"B\":')

lado_b = float(input())

hipotenusa = math.hypot(lado_c, lado_b)

print('-------------------------------')

print(f'Lado A =  {round(hipotenusa,3)}')

y = math.atan(lado_c / lado_b)
y = math.degrees(y)
x = 90 - y

print('')

print('Angulo X = ', round(x, 2))

print('')

print('Angulo Y = ', round(y, 2))
