Miranda is a wonderful Shape Designer. Below are some of the orders she has received. For each order, draw at least two different shapes that fit the description.

1. An acute triangle that is also an isosceles triangle.

   Help (a):

   One example of this is below. Can you think of another way to draw this order?

   

2. A shape with two obtuse angles and four sides.

   Hint (b):

   Remember that an obtuse angle is one whose measure is between $90^\circ$ and $180^\circ$.

   Answer (b):

   Be sure to draw another shape to fit this order!

   

3. A pentagon with at least one acute and one obtuse angle.

   Hint (c):

   Remember that a pentagon has $5$ sides.
