Work Step by Step

The sum of the measures of the angles of a parallelogram is 360°.The sum of the measures of the angles of a triangle is 180°. Write an inequality statement using $\leq$ or $\geq$ comparing the numbers 360 and 180. We know that 360 is to the right of 180 on the numberline, therefore 360 is greater than ($\gt$) or equal to (=) 180. Combining $\gt$ and = gives us $\geq$ Result: 360$\geq$180
