In order to prove that two triangles are congruent using the ASA theorem, it is necessary to show two pairs of congruent angles and one pair of congruent sides of the triangles.
In the given diagram, there is already a pair of congruent triangles and a pair of congruent sides shown.
Then, in order to use the ASA theorem, we need to prove that there is another pair of congruent angles, one from each triangle.
Since the side VX must be adjacent to both angles involved in the procedure, then we need to show that the angle VXW is congruent to the angle YXZ, which is adjacent to the side YX.
This can be proven using the fact that VXW and YXZ are vertical angles.
Therefore, the necessary step in Johnny's proof is shown in option D)
Heat can be moved from one place to another by 3 methods: cunduction, which happends in solids, convection, which happends in fluids, and radiation. Conduction occurs when two objects are touching each other. Heat moves from the hot object to the cold object until the two objects are the same temperature. Convection happends when hotter areas of a liquid or gas rise to the colder areas. Both conduction and convection require some form of matter but radiation does not. Radiation does not rely on things in contact with a heat source and what is being heated. For example, we feel the sun everyday and it feels hot but we never touch it.
