Answer from: batmanmarie2004

parallelogram
kite
rhombus

Explanation:
Let's check each of the given choices:
1- Square:
It is a quadrilateral in which all sides are equal, each two opposite sides are parallel and all angles are equal to 90°. Therefore, this option is not correct

2- Rectangle:
It is a quadrilateral in which each two opposite sides are equal and parallel and all angles are equal to 90°. Therefore, this option is not correct

3- Parallelogram:
A quadrilateral in which each two opposite sides are equal and parallel. Two consecutive angles cannot be 90°, because it would then become a rectangle. Therefore, this choice is correct

4- Kite:
A quadrilateral in which each two opposite sides are equal and parallel. Two consecutive angles cannot be 90°, because it would then become a rectangle. Therefore, this choice is correct

5- Rhombus:
A quadrilateral in which all sides are equal, each two opposite sides are parallel. Two consecutive angles cannot be 90°, because it would then become a square. Therefore, this choice is correct

6- Trapezoid:
It is a quadrilateral in which two sides are parallel. If it is a right trapezoid (like the attached picture), then two consecutive angles would be equal to 90°. Therefore, this choice is not correct

Hope this helps :)

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
