explain how the area of a triangle is related to the area of a parallelogram

Question

help me answer my question please some one help me!

 

Answer 1

Area of Parallelogram = base*height

 

If you draw a diagonal across the parallelogram from one vertex to the opposite vertex, you divide the parallelogram into two congruent triangles.  Each triangle thus has 1/2 of the area of the parallelogram.

 

Area of Triangle = (1/2)*base*height
