The answer will depend on the exact shapes of the individual items.
A pentagon (a shape with 5 sides). Just stack the shapes ontop of eachother.
You can make 5 triangles out of 9 toothpicks. With 6 toothpicks, make a large triangle with 2 toothpicks for each side. Now, take individual toothpicks, and make a smaller triangle inside the larger one by joining the midpoints of the sides of the previous triangle. (The vertices of the smaller triangle are the midpoints of the sides of the larger one).
Make 5 shapes using Tangrams.
The answer depends on the 5 shapes. Unfortunately, you have not specified what they are and so the question cannot be answered. - which

3, 5, 5 does not make a right angle triangle but they can make an isosceles triangle Correct. Try 3,4,5. That will be a right triangle. 3x3 plus 4x4 = 5x5

Yes, take a square, cut into 5 shapes.
there isn't a polygon with 3 sides but there are triangles. polygons start with hexgons; 5 sided shapes.
