I think a right triangle?

Answer 1

not if it doesn't have a right (\(90^\circ\)) angle it isn't

Answer 2

An acute?

Answer 3

all the angles are equal so we call it an equilateral triangle

Answer 4

@dan815 that is when we have equal sides

Answer 5

We are talking about ANGLES here

Answer 6

So this would be a right triangle?

Answer 7

if all angles are than 90 its acute one larger than 90 its obtuse

Yes

Answer 9

if there is one angle 90 its a right triangle

Answer 10

You can use this to help :)

Answer 11

This is an equalaterial triangle

Answer 12

No it's not.

Answer 13

The very first triangle is an equiangular triangle.

Answer 14

Yes agree @Directrix

Answer 15

It could be tricky if there are options.

Answer 16

Agreed.
It is not an equilateral because that is referring to the sides.
I personally think acute. All angles are less than 90 degrees

Answer 17

@pooja195 is right but I'm sorry for not listing the choices, the three choices were obtuse, acute and right.

Answer 18

Right so you were correct about acute

Answer 19

Which is indeed correct.

Answer 20

https://en.m.wikibooks.org/wiki/Trigonometry/Angles_of_a_triangle_sum_to_180_Degrees But if it asked it would be too

Answer 21

If the triangle is equiangular, then it has to be acute.

And, equiangular is a stronger statement.

Again, I don't know if the OP's question has options. If he is choosing from among acute, right, and obtuse, then clearly it would be acute for the very first triangle.

Answer 22

That's the only way you would get 3 60 degree angles

Answer 23

A triangle is 180 degrees.

Answer 24

@ProMiner10000 Look in your text and tell us the instructions for these problems. Thanks.

Answer 25

@Directrix they already said that they forgot to add answer choices.

Answer 26

Yes I get that 3 60 angles =180 degrees it's just there's no way you can have all the same angles without having same side lengths

The OP was right. Acute.
