Constructing Shapes With the Same Area
What You Learned
Learning Goal
I can build parallelograms, triangles, rectangles, and squares with any reasonable area that I am given.
Lesson Summary
• 
You can build different kinds of shapes with a specific area.


• 
No matter what the area is, you can follow the same steps to build a shape.


• 
The product of the base and height is the area of a parallelogram, including a rectangle and a square, but it is twice the area of a triangle.

Key Terms
area: the amount of space in a 2D shape; the number of 2D units that will cover this space
parallelogram: a quadrilateral that has two pairs of parallel and equal sides
rectangle: a parallelogram with four right angles
square: a rectangle with four equal sides; also a rhombus with four right angles
