Ineed with the following two questions this is a desperate situation and it vance see attached images

Parallelogram with four congruent sides

Step-by-step explanation:

Rhombus: It is special type of quadrilateral whose all sides congruent and opposite sides are parallel.

Diagonals of rhombus are perpendicular bisector. Diagonals make angle 90 degree at intersection point.

Rhombus is a parallelogram with four congruent sides.

Attached image is show shape of rhombus.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

i suppose it should be (y=2x-5)
