Classify an equiangular triangle by its angles. Choose one answer. a. right b. acute c. obtuse d. cannot be determined

OpenStudy (anonymous):

i think the answer is A

OpenStudy (anonymous):

i just wanna be assured

Directrix (directrix):

@janessia --> What is the sum of the interia angle measures of a triangle?

OpenStudy (anonymous):

180

Directrix (directrix):

Good. If a triangle is equiangular, then that means its angles all have the same measure. Do you agree?

Directrix (directrix):

Yes or no?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

and its equilateral too

Directrix (directrix):

Good. If the three angles sum to 180 and all three have the same degree measure, then each angle has measure what?

OpenStudy (anonymous):

90?

Directrix (directrix):

If each angle has measure x, then x + x + x = 180. Okay, solve x + x + x = 180 for x. Then you will know what the angle measures are and what kind of triangle this is. Stay with me --> What does x equal?

Directrix (directrix):

x + x + x = 180 3x = 180 x = ?

OpenStudy (anonymous):

60

Directrix (directrix):

Is an angle of measure 60 an acute angle, a right angle, or an obtuse angle?

OpenStudy (anonymous):

acute

Directrix (directrix):

That is correct. I am uploading a "Classification of Triangles" chart for you to study.

OpenStudy (anonymous):

WOW thanks so much!!

Directrix (directrix):

Glad to help.
