Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Identify the type of angle.
2	Step	The given image shows the acute angle.
3	Step	This is an angle that measures less than 90 degrees is called acute angle.
4	Step	Compare the given options with the definition of acute angle.
5	Hint	An acute angle is any angle less than 90 degrees.
6	Step	So the given image shows a acute angle.
7	Sumup	Can you summarize what you’ve understood in the above steps?
8	Choice.A	This is incorrect because a right angle is an angle that measures exactly 90 degrees	Right angle
9	Choice.B	This is incorrect because an obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees	Obtuse angle
10	Choice.C	This is correct because it is an angle that measures less than 90 degrees is called acute angle	Acute angle
11	Choice.D	This is incorrect because as this option implies that the angle is not a right angle, obtuse angle, or acute angle	None of the above
12	Answer	Option	C
13	Sumup	Can you summarize what you’ve understood in the above steps?

Answer

Problem

Identify the type of angle.

Step

The given image shows the acute angle.

Step

This is an angle that measures less than 90 degrees is called acute angle.

Step

Compare the given options with the definition of acute angle.

Hint

An acute angle is any angle less than 90 degrees.

Step

So the given image shows a acute angle.

Sumup

Can you summarize what you’ve understood in the above steps?

Choice.A

This is incorrect because a right angle is an angle that measures exactly 90 degrees

Right angle

Choice.B

This is incorrect because an obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees

Obtuse angle

Choice.C

This is correct because it is an angle that measures less than 90 degrees is called acute angle

Acute angle

Choice.D

This is incorrect because as this option implies that the angle is not a right angle, obtuse angle, or acute angle

None of the above
