The shapes that have two obtuse angles is required.

The required shapes are 1, 3 and 4.

An angle which is greater than $90^{\circ}$ is called an obtuse angle.

1. The shape is a parallelogram.

$\angle B$ and $\angle D$ are greater than $90^{\circ}$ .

So, it does have two obtuse angles.

2. The shape is a rectangle.

Each interior angle is $90^{\circ}$ .

So, it does not have any obtuse angles.

3. The shape is a trapezoid.

$\angle A$ and $\angle B$ are greater than $90^{\circ}$ .

So, it does have two obtuse angles.

4. The shape is a parallelogram.

$\angle B$ and $\angle D$ are greater than $90^{\circ}$ .

So, it does have two obtuse angles.

5. The shape is a trapezoid.

$\angle D$ is greater than $90^{\circ}$ .

It has only one angle greater than $90^{\circ}$ .

So, it does not have two obtuse angles.

6. The shape is a square.

Each interior angle is $90^{\circ}$

So, it does not have any obtuse angles.

The numbering and corner points of the shapes are shown in the figure attached.
