Question

why shouldn’t you tell a pigeon a secret? b
write the letter of each answer in the box containing the exercise number.
use the diagram to identify an angle with the given classification.

1. right angle
2. obtuse angle
3. straight angle
4. acute angle

Explanation:

Step1: Recall angle - definitions

A right - angle measures 90 degrees, an obtuse angle measures more than 90 degrees but less than 180 degrees, a straight angle measures 180 degrees, and an acute angle measures less than 90 degrees.

Step2: Identify right - angle

In the diagram, $\angle AFC$ and $\angle CFE$ are right - angles since they are marked with the right - angle symbol. So for a right - angle, one answer could be $\angle AFC$.

Step3: Identify obtuse - angle

$\angle AFD$ is an obtuse angle as it is greater than 90 degrees and less than 180 degrees.

Step4: Identify straight - angle

$\angle AFE$ is a straight angle as it is a flat line and measures 180 degrees.

Step5: Identify acute - angle

$\angle BFC$ is an acute angle as it is less than 90 degrees.

Answer:

1. $\angle AFC$
2. $\angle AFD$
3. $\angle AFE$
4. $\angle BFC$
