Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
All isosceles triangles are also equilateral triangles?
No, all isosceles triangles are not equilateral triangles. An isosceles triangle is a triangle that has two sides of equal length. An equilateral triangle is a triangle that has all three sides of equal length. Therefore, it is possible for a triangle to be isosceles but not equilateral. For example, a triangle with sides of lengths 3, 3, and 4 is an isosceles triangle, but it is not an equilateral triangle because all its sides do not have the same length. On the other hand, all equilateral triangles are also isosceles triangles because they have two sides of equal length. My recommendation ʜᴛᴛᴘꜱ://ᴡᴡᴡ.ᴅɪɢɪꜱᴛᴏʀᴇ24.ᴄᴏᴍ/ʀᴇᴅɪʀ/372576/ꜱᴀɪᴋɪʀᴀɴ21ᴍ/
Are some scalene triangles also isosceles triangles?
Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.
Are all equilateral triangles also isosceles triangles?
Yes, an isosceles triangle is a triangle that has at least two congruent sides.
Are all isosceles triangles also equilateral triangles?
No, not at all, all isosceles triangles aren't equilateral since an equilateral triangle is a triangle with all of its sides equal, i.e. all sides of an equilateral triangle are equal, but in an isosceles triangle only two of its sides are equal.
Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
Are some isosceles triangles equilateral triangles?
All isosceles triangles are not equilateral triangles
Are all right triangles an isosceles triangles?
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
Are all triangles semmetrical?
No. But all isosceles triangles and equilateral triangles are.
Are all right triangles isosceles triangles?
no
Is it true that all isosceles triangles can be equilateral triangles?
No
All isosceles triangles are also equilateral triangles?
No, all isosceles triangles are not equilateral triangles. An isosceles triangle is a triangle that has two sides of equal length. An equilateral triangle is a triangle that has all three sides of equal length. Therefore, it is possible for a triangle to be isosceles but not equilateral. For example, a triangle with sides of lengths 3, 3, and 4 is an isosceles triangle, but it is not an equilateral triangle because all its sides do not have the same length.

Are all equilateral triangles also isoscelles triangles?
Yes. But not all isosceles triangles are equilateral.
Can equilateral triangles be isosceles triangles?
no. Equilateral triangles have all equal sides. Isoceles triangles only have 2 congruent sides. Isosceles triangles have 2 equal sides.
Are some scalene triangles also isosceles triangles?
Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.
Are all equilateral triangles isosceles true or false?
False. Equilateral triangles are equilateral. All isosceles triangles have two of the sides the same, with the hypotenuse being longer than the other two.
Are all acute triangles isosceles triangles.?
No because a triangle is only an isosceles triangle when it has 2 equal sides
