Which set of statements would describe a parallelogram that can always be classified as a rhombus? I. Diagonals are perpendicular bisectors of each other. II. Diagonals bisect the angles from which they are drawn. III. Diagonals form four congruent isosceles right triangles. 1. I and II 2. I and III 3. II and III 4. I, II, and III

1. I, II,

Step-by-step explanation:

I. Diagonals are perpendicular bisectors of each other  

Yes, because 4 sides are congruent so it makes the two diagonals perpendicular bisectors

II. Diagonals bisect the angles from which they are drawn

Yes, That is the property of the diagonal!

III. Diagonals form four congruent isosceles right triangles.

No, only two pairs of right triangles are congruent and sometime the side of each pair are different to each other.

Hence, we choose I and II

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

answer: y=0 if that is what u r looking for
