An equilateral triangle has to be acute. All the sides are the same size, and all the angles are the same size. You can't have three 90 degree angles in a triangle or three angles that are more than 90 degrees in a triangle. Therefore the angles have to be acute.
An isosceles triangle will have two angles at are the same size. You can't have two 90 degree angles or two angles over 90 degrees in a triangle, but the triangle only has to have one of those angles to be either right or obtuse. The right or obtuse angle must be between the two sides that are equal and the two angles that are equal have to be acute. So then an isosceles triangle can be any of the three - acute, obtuse, or right.
A scalene triangle has three unequal sides. Therefore, the angles will all be unequal. Can you think of any three angles that are all less than 90 degrees that will add up to 180 degrees? (acute?)
What about any two angles (not equal) that will add to another 90 degree angle to make 180 degrees? (right?)
What about any two angles (not equal) that will add to another angle larger than 90 degree to make 180 degrees? (obtuse?)
Therefore there are 7 possible combinations.

Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
What are three different types of triangles?
equilateral,isosceles and scalene
What is the contrapositive of the statement if it is an equilateral triangle then it is an isosceles triangle?
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
If a triangle is equilateral then it is isosceles What is the converse of the statement?
If a triangle is isosceles, then it is equilateral. To find the converse of a conditional, you switch the antecedent ("If ____ ...") and consequent ("... then ____."). (Of course, if not ALL isosceles triangles were equilateral, then the converse would be false.)
Can a scalene triangle be isosceles?
No. An equilateral triangle is also isosceles, but isosceles is not scalene.
How is an isosceles triangle different from an equilateral triangle?
Isosceles has 2 equal sides, but an equilateral triangle, all of its sides are equal.
Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
How is an isosceles triangle different then an equilateral triangle?
A equilateral triangle has all equal sides, while an isosceles triangle only has 2 equal sides.
How are equilateral triangles and isosceles triangles different?
Equilateral triangles have 3 equal sides whereas isosceles triangles have only 2 equal sides
What are three different types of triangles?
equilateral,isosceles and scalene
Are some isosceles triangles equilateral triangles?
All isosceles triangles are not equilateral triangles
Why is equilateral triangle not isosceles?
The definition of an isosceles triangle is that 2 sides are the same length, the other is different. An equilateral triangle means all sides are the same.
What are the three types of triangles?
equilateral, isosceles and scalene
Is a right triangle an equilateral scalene or isosceles triangle?
It can be scalene or isosceles but not equilateral.
What does Isosceles Triangle and Equilateral Triangle have that is different?
Equilateral triangles have 3 equal sides, but isosceles only have two equal sides. Also, equilateral triangles have three 60° angles. Isosceles triangles have two congruent base angles and a vertex angle.
Are All equilateral triangles are isosceles.?
No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides
Are isosceles triangle sometimes an equilateral triangle?
Are isosceles triangle sometimes an equilateral triangle
