What additional information do you need to prove ∆ABC ≅ ∆DEF by the SAS Postulate?

A.) ∠CAB ≅ ∠FDE

B.) ∠BCA ≅ ∠EFD

C.) ∠ABC ≅ ∠DEF

A.) ∠CAB ≅ ∠FDE

Explanation:

The Side Angle Side (SAS) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the two triangles are congruent.

In this case, the sides  are AB ≅ DE and   CA ≅ FD

The included angles are ∠CAB ≅ ∠FDE

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

think its the third option
