Answer:

1. All parallelograms are quadrilaterals

Step-by-step explanation:

A quadrilateral is defined as any 4-sided polygon. Parallelograms are quadrilaterals in which opposite sides are parallel. So any 4-sided polygon such as squares, rectangles, trapezoids, rhombuses, etc., are all quadrilaterals. ... You'll always get a parallelogram!

Hope I helped :)

The measure of an interor angle of a regular polygon is given. Find the number of sides in the polygon.

EleoNora [17]

Let side be n

#1

$\\ \sf\longmapsto 120n=(n-2)180$

$\\ \sf\longmapsto 120n=180n-360$

$\\ \sf\longmapsto -60n=-360$

$\\ \sf\longmapsto n=6$

#2

$\\ \sf\longmapsto 160n=(n-2)180$

$\\ \sf\longmapsto 160n=180n-240$

$\\ \sf\longmapsto -20n=-240$

$\\ \sf\longmapsto n=12$

#3

$\\ \sf\longmapsto 144n=(n-2)180$

$\\ \sf\longmapsto 144n=180n-360$

$\\ \sf\longmapsto -36n=-360$

$\\ \sf\longmapsto n=10$
