Task: In parallelogram FGHI, what is the degree
measurement of < IFG?
Type your answer into the text box, and then click Continue.
<
IFG = 105
Since opposite angles in a parallelogram are equal, we know that
< IFG
has the same degree measurement as < IHG.
To find < IHG,
we need to know the value of a. Since adjacent angles in
a parallelogram are supplementary, we know that 15a + 5a
+ 80 = 180. We can solve for a:
20a = 100
a = 5
< IHG
and therefore < IFG,
have a degree measurement of 5(5) + 80 = 105.
