Respuesta :

angle <1 ≅ <2 because vertical angles are congruent, CD ≅ BD because a midpoint divides a line segment into two congruent segments.

Step-by-step explanation:

1. Mark the angles formed by the bisecting lines with a "(" and ")" and label both with the numbers 1 and two for each angle to show that there are two angles and that they are congruent to eachother.

___

1. put vertical lines through the middle of CD and DB to indicate they are both congruent.

Answer:

Look below.

Step-by-step explanation:

1. Line CE ≅ Line BF

If Line CE bisects Line AB and Line BF bisects CD and if Quadrilateral ABCD is a rectangle.

2. If D is the midpoint of Line BC then we get:

Line BC ≅ Line AD ≅ Line AB ≅ Line AC
