Examine the arrow diagram below.
Polygon is a parallelogram → area of the polygon equals base times height.
Write this conjecture as a conditional (“If, then”) statement.
Write a similar conjecture about triangles, both as a conditional statement and as an arrow diagram.
If a polygon is a parallelogram, then its area equals its base times its height.
If a polygon is a triangle, then its area equals one half its base times its height.
