One and the two others are acute angles
A isosceles triangle can have two equal angles, but an equilateral triangle is actually a special isosceles triangle, so it could also have 3.
three * * * * * Actually, it is 2 ******* Actually it is 3 because an equilateral triangle is a special isosceles triangle, and they have 3 equal angles

An Isosceles Triangle is a triangle with all angles less than 90o So there are no obtuse angles (between 90o to 180o).
check wikapedi!
It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).
In an isosceles triangle, two of the angles are the same.
An obtuse triangle can have no right angles, and has two equal angles.
there are three angles on an isosceles triangle
A triangle can have at most one obtuse angle, but triangles do not necessarily have any obtuse angles.
No right triangle can have any obtuse angles inside it.
Isosceles has two congruent angles.
there is many ways to write when classifying a triangle, you can classify it by its sides or angles. When you classify it by angles you can classify it by acute, obtuse, and right triangle. when classyfing it by sides its isosceles, equilateral, and scalene!
Triangles can be classified based on their sides and angles. Based on sides, triangles can be equilateral (all sides are equal), isosceles (two sides are equal), or scalene (no sides are equal). Based on angles, triangles can be acute (all angles are less than 90 degrees), obtuse (one angle is greater than 90 degrees), or right (one angle is exactly 90 degrees).
Isosceles triangle have two equal angles2
