In a quadrangle, the line connecting two opposite corners is called a diagonal. We will show that in a parallelogram, each diagonal bisects the other diagonal.

Problem

ABCD is a parallelogram, and AC and BD are its two diagonals. Show that AO = OC and that BO = OD

answer: bea's uncle is 25 years old.

therefore, we can conclude that bea's uncle is 25 years old.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
