Best ResponseYou've already chosen the best response.0Corresponding parts of a triangle are congruent...? right?

Best ResponseYou've already chosen the best response.1Correct, Corresponding parts of congruent triangles are congruent. What do you think this means for \(\triangle{ABC} \cong \triangle{DEF}\) ?

Best ResponseYou've already chosen the best response.0that equal sign with the squiggly thingy means that they correspond so triangle ABC corresponds to triangle DEF?

Best ResponseYou've already chosen the best response.1Well, @pooja195, here's a bit of insight for you: \(\triangle{ABC} \cong \triangle{DEF}\) means the following: \(\angle{A} \cong \angle{D}\) \(\angle{B} \cong \angle{E}\) \(\angle{C} \cong \angle{F}\) \(\overline{AB} \cong \overline{DE}\) \(\overline{BC} \cong \overline{EF}\) \(\overline{AC} \cong \overline{DF}\)

Best ResponseYou've already chosen the best response.1The corresponding angles have the same measure and the corresponding segments have the same length.

Best ResponseYou've already chosen the best response.1I think what you meant to say is that since \(\overline{AC} = 5\) then \(\overline{DF} = 5\)

Best ResponseYou've already chosen the best response.1@pooja195, what does the problem ask us to find?

Hero

Best ResponseYou've already chosen the best response.1Okay, and we found \(\overline{DF}\). Now we have to find \(m\angle{B}\). Any ideas on that at all based on what was explained above?

Best ResponseYou've already chosen the best response.1B and E correspond with each other and therefore have the same measure.

Best ResponseYou've already chosen the best response.1\(m\angle{E} = 100^{\circ}\), therefore \(m\angle{B} = 100^{\circ}\). That's how you would say it properly. Saying just "100 degrees" isn't really saying anything other than just "announcing" 100 degrees. Somebody might think you're referring to the temperature outside.
