In right triangle efg, me = 25. in right triangle hjk, mh = 25. which similarity postulate or theorem proves that efg and hjk are similar?

The postulate or theorem which proves that EFG and HJK triangles are similar is Angle-Angle  (AA)

according to it

In case of two triangles if two pairs of corresponding angles are congruent, the triangles are considered to be similar triangles.

c is the answer because when something is left after something evaporates that shows the chemical change.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
