Since, AD ≅ BC, ∠BCD ≅ ∠ADC and segment CD ≅ DC, △ADC ≅ △BCD by SAS. Therefore, based on CPCTC, DE ≅ CE.

Explanation:

  • We are given AD ≅ BC and ∠BCD ≅ ∠ADC.
  • The segment CD is common for △ADC and △BCD.
  • This means BCD and ADC are isosceles triangles.  
  • Therefore, we can say that △ADC ≅ △BCD by SAS.
  • Because of CPCTC, segment DE is congruent to segment CE.
  • Hence, based on the isosceles triangle theorem, DE ≅ CE.

How is amplified warming different from natural warming
sladkih [1.3K]
The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Normal warming is mostly caused by natural gases.
