Question

1. use the angles from problem 1 as examples to write a description of the angle term.

angles | examples | description
--- | --- | ---
right angle | $\angle abc$, $\angle ijl$ |
obtuse angle | $\angle hfg$, $\angle ijm$ |
acute angle | $\angle abd$, $\angle ljm$ |
straight angle | $\angle efg$, $\angle ijk$ |
complementary angles | $\angle abd$ and $\angle dbc$, $\angle ljm$ and $\angle mjk$ |
supplementary angles | $\angle efh$ and $\angle hfg$, $\angle ijm$ and $\angle mjk$ |

Explanation:

Each description is based on the standard geometric definition of the angle type, aligned with the given examples.

Answer:

Angles	Examples	Description
obtuse angle	$\angle HFG, \angle IJM$	An angle greater than $90^\circ$ but less than $180^\circ$
acute angle	$\angle ABD, \angle LJM$	An angle less than $90^\circ$
straight angle	$\angle EFG, \angle IJK$	An angle equal to $180^\circ$, forming a straight line
complementary angles	$\angle ABD$ and $\angle DBC$, $\angle LJM$ and $\angle MJK$	A pair of angles whose sum equals $90^\circ$
supplementary angles	$\angle EFH$ and $\angle HFG$, $\angle IJM$ and $\angle MJK$	A pair of angles whose sum equals $180^\circ$
