Best Answer

No.

Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:

- Isosceles triangles which have two equal angles and two equal sides;
- Scalene triangles which have all three sides, and hence all three angles, of different lengths;
- Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.

All isosceles triangles are not equilateral triangles

Yes all equilateral triangles are acute triangles, but not all acute triangle are 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/

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.

no. if one triangles sides are all 2 and one triangles sides are all 3 then they are not congruent

Yes. But not all isosceles triangles are equilateral.

Triangles are equilateral triangles only when all of their 3 sides are equal in lengths.

Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.

No. But all isosceles triangles and equilateral triangles are.

No, but all equilateral triangles are acute. Acute: All angles of the triangle are less than 90 degrees. Equilateral: All angles of the triangle are 60 degrees.

No

No, not all isoceles triangles can be equilateral triangles because an equilateral triangle has sides that are all equal to each other and an isoceles triangle has only two sides that are equal to each other.

False. Equilateral triangles are equilateral. All isosceles triangles have two of the sides the same, with the hypotenuse being longer than the other two.
