Explanation:
To solve this, we need to identify each triangle as acute, right, or obtuse based on its angles.
First, let’s remember the definitions:
- An
acute triangle has all three angles less than 90 degrees.
- A
right triangle has one angle exactly 90 degrees.
- An
obtuse triangle has one angle greater than 90 degrees.
Now, look at each triangle:
a. This triangle has one angle that looks bigger than 90 degrees. So it is
obtuse.
b. This triangle looks like it has a right angle (one angle is 90 degrees). So it is
right.
c. This triangle has all angles less than 90 degrees. So it is
acute.
d. This triangle has one angle that is clearly greater than 90 degrees. So it is
obtuse.
e. This triangle has all angles less than 90 degrees. So it is
acute.
f. This triangle has one angle that looks like it’s exactly 90 degrees. So it is
right.
Final Answer:
a. obtuse
b. right
c. acute
d. obtuse
e. acute
f. right
