**1. All triangles lying between two parallel lines and built on the same base have equal area.**

If AB and CF are parallel lines,

**
**

**∆ABC = ∆ABD = ∆ABE = ∆ABF**

**2. All parallelograms lying between two parallel lines and built on the same base have equal area.**

If AB and CH are parallel lines,

o

**ABEC =**o**ABGD =**o**ABHF**
