Answer: ASA Postulate
Explanation:
GIVEN: ∠D congruent to ∠T,
∠E congruent to ∠U,
DE congruent to UT
Now, in ΔUXT and ΔDOE
∠D congruent to ∠T [Angle]
DE congruent to UT [included side]
∠E congruent to ∠U [Angle]
By ASA postulate of congruence , ΔUXT ≅ ΔDOE
- ASA Postulate of congruence says that if two angles and the included side of a triangle are congruent to two angles and the included side of other triangle then the triangles are said to be congruent.
