Question

By simply looking at the pairs of angles given in the figure, state which angle in each of the pairs is greater:

Answer 1

We know that the angle whose measure is $90°$is a right angle and the angle whose measure is greater than $90°$ is an obtuse angle.

Here, $\angle ABC$ is greater than $90°$ i.e., an obtuse angle, and $\angle DEF$ is $90°$ i.e., right angle.

Hence, $\angle ABC$ is greater than $\angle DEF$.
