2-103.

Examine the arrow diagram below.

Polygon is a parallelogramarea of the polygon equals base times height.

  1. Write this conjecture as a conditional (“If, then”) statement.

  2. 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.
