Question

14.1: math talk: comparing angles
for each figure, which pair of angles appears congruent?
how could you check?
1.
cba and fed appear congruent. check by measuring with a protractor
2.

Explanation:

Step1: Observe the angles

Visually inspect the given angle - pairs in each figure.

Step2: Identify congruent - looking pairs

In the first set of angles, $\angle CBA$ and $\angle FED$ seem to have the same opening.

Step3: Suggest a verification method

To confirm congruence, use a protractor to measure the angles. If the measures are equal, the angles are congruent.

Answer:

1. $\angle CBA$ and $\angle FED$ appear congruent. Check by measuring with a protractor.
2. (No answer provided for part 2 in the question - if we were to follow the same process, we would first observe the angles in the second set of figures, identify the pair that appears congruent visually, and suggest measuring with a protractor to check. For example, if $\angle YZM$ and $\angle SIR$ appear congruent visually, we would say: $\angle YZM$ and $\angle SIR$ appear congruent. Check by measuring with a protractor.)
