Select the correct answer from each drop-down menu. If AB = DECA = FDangle B is congruent to angle Eangle A is congruent to angle D, then ∆ABC and ∆DEF are congruent by the ASA criterion.
If AB = DEangle B is congruent to angle ECA = FDangle A is congruent to angle D, then ∆ABC and ∆DEF are congruent by the SAS criterion.
∆ABC and ∆DEF are congruent if angle A is congruent to angle DAB = DEAB = DF.

da freeck kinda math is this just drop out

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
