An Equilateral Triangle
You cannot have an isosceles trinangle with 60 degrees sides
An equilateral triangleequilateral
A scalene triangle. In a scalene triangle, there are no congruent sides or angles. In an isosceles triangle, at least two congruent sides and angles. In an equilateral triangle, all three sides and angles are congruent, with angles that always measure sixty degrees. Note: an equilateral triangle also classifies as an isosceles triangle, as it meets the definition of an isosceles triangle mentioned above.
If its other two angles are 25 degrees and 90 degrees then it is a right angle triangle.
40 degrees
No, else the sides would not be able to close. Triangles may only have one right angle, at any given time. For a triangle to have exactly equal angles; each angle would have to measure sixty degrees - which is known as an equilateral triangle.
Isosceles.Improved Answer:If it has two 60 degree angles then the third angle must be 60 degrees because there are 180 degrees in a triangle.So it will be an equilateral triangle.
The three basic types of triangles are equilateral, isosceles, and scalene. An equilateral triangle has three congruent (equal) sides and three sixty-degree angles. An isosceles triangle has two congruent sides and the two angles opposite those sides are also congruent. A scalene triangle has no congruent sides or angles.
The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson
A triangle has three angles, not "angels." The sum of the angles will equal one hundred eighty degree. An equilateral triangle has three equal angles all measuring sixty degrees.
An octagon has 8 sides, not 6, and each internal angle is 45 degrees. A hexagon has 6 sides, and the internal angle between each side is sixty degrees.
As a hexagon has six sides, it also has six angles. Three hundred sixty dgrees make a complete circle, so three hundred sixty degrees divided by six angles makes... sixty degrees each. Oddly, if you draw six equilateral triangles with sides of equal length, and put them together, they will visually display to you what I explained above as a hexagonal shape.
