In quadrilateral ABCD diagonals intersect at point T Jasmine used to alternate interior angles theorem to show that angle DAC is congruent to angle BCA  and that angle ADB is congruent to CBD. Which of the following can Jasmine use prove that triangle ATD is congruent to triangle CTB?

AB ≈= DC

AC ≈= DB

DA ≈= BC

TA ≈= TC

B: AC=DB

Step-by-step explanation: If AC is congruent to DB then we can conclude that ATD is congruent to triangle CTB.

DC = AB

Step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
