**A**

__QUADRILATERAL__is a polygon with 4 sides and 4 angles.**Different types of quadrilaterals are parallelograms, rectangles, squares, rhombuses, and trapezoids.**

In this

**experiment,**students will

**predict**the

**sum**of all 4 interior angles of a particular quadrilateral. Then they will

**predict**if the different kinds of quadrilaterals have the same

**sum**for their interior angles.

**Materials**- paper
- pencil
- marker (optional)
- ruler
- protractor
- scissors

__Directions__- Have students
**draw**3 different types of quadrilaterals and**cut**out each one.

**Mark**each angle. Use a square for right angles and a curved line for all other angles.

- Have the student
**choose**one of the quadrilaterals. **Predict**the**sum**of all 4 interior angles.**Cut**off the corners (angles) of the quadrilaterals.

**Place**the cut pieces together with the angles touching each other.**Observe!**

- What is the
**sum**of all 4 angles? - Next
**predict**if the answer will be the same for the other quadrilaterals. **Repeat**the steps above for the other quadrilaterals- Was the
**prediction**correct? What is the**sum**of the interior angles in a quadrilateral?

*The sum of all the angles in a quadrilateral = 360 degrees.*

__Extension Activity__:

**Try the above experiment with a pentagon, hexagon, and/or octagon.**

*Have fun with geometry!*

I am here to give the definition and properties of quadrilaterals as they are figures with four sides and four angles. There are many different types of quadrilaterals, which are classified by their sides and angles here are some examples-rectangle, parallelogram, trapezoid, rhombus, square and kite.
