Draw a parallelogram that has side lengths of 2 inches and 1 inch and which has angle measures of 120° and 60°.

we are going to begin our parallelogram by drawing a horizontal line of two inches; then, we are going to place a protractor at the beginning of the line and measure an angle of 120°. next, we are going to use a ruler to draw  the 1-inch line. now, the only thing we have  left is draw the other two parallel lines. 

since two adjacent angles of a parallelogram are supplementary, the other adjacent angle will measure 60°, so we will not need to use a protractor  a second time.

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