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.

Lava, ash, and other materials from volcanic eruptions gradually build up over time. This is the correct answer. The volcanic molten material is ejected from fissures or initial cones and as the lava flows out and cools and as the pyroclastic materials solidify and tumble down the slopes, they build up the flanks of the volcanoes.</span>
Some of the Europeans came to New France (Canada) because they wanted to support and promote or possibly change the First Nations into Romon Catholics, these people included the Jesuit priests and the Ursuline nuns. Explorers like Jaques Cartier and Samuel de Champlain came for riches and routes to Asia. Couriers de bois AKA runners of the woods came to New France for Fur Trade. Hope this helped
