An acute angled triangle.
Regular, Acute, and Equilateral * * * * * Regular and Equilateral are correct but not Acute. An acute triangle with angles of 50,60 70 degrees for example, is not regular. An equiangular triangle is the third possible name.
Acute scalene triangle
For one thing, it's an "acute triangle" because all three of its angles are acute. But in the very special case where all three angles are 60 degrees each, the triangle's sides are also all the same length, and that characteristic is the root of it's name. It's called an "equilateral" triangle, even though it's also an "equiangular" triangle.
An acute angled triangle, right angled triangle or obtuse angled triangle.
An acute angled triangle.
The name of a triangle is dependent on the type of angles within it. If it has a right angle it is called a right triangle, if it has an obtuse angle it is an obtuse triangle, and if all three sides are acute it is an acute triangle.

it is either an equilateral triangle, or an isosceles triangle.

An acute angled triangle, right angled triangle or obtuse angled triangle.
It can be an obtuse triangle which includes 2 acute angles and the 3 angles add up to 180 degrees
a trignal has 3 sides is it trilateral other wise it depends on the angles and sides eg a acute angle triangle, a equalateral triangle, a scalene triangle
Tri means three, and there are three angles to a triangle so that's how the triangle got its name.
how you name a triangle by its angles is like acute, obtuse, or right triangle. you do that by seeing if the angle has a 90 degree angle in it then its a right angle, if all the angles are 90 degrees or less than its an acute triangle. and if the triangle has one angle that is over 90 degrees than it is an obtuse triangle. to name a triangle by its sides is if its equilateral, equiangular, or regular. if its equilateral then all the sides are congruent. if its equiangular then all the angles are congruent. if its regular, then all the sides and angles are congruent to each other (for example and octogon). :)
Tri means three. And there are three angles to a triangle.
