True or false all isosceles triangles are also equilateral triangles?
False.
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.
Is it true or false that an isosceles triangle may have a right angle?
It is true.
In an isosceles triangle if a base angle has a measure of 43 degrees then the vertex angle must have a measure of 80 degrees as well true or false?
False because if each base angle is 43 degrees then the apex angle must be 94 degrees
Can an isosceles triangle be scalene?
it's false that the isosceles triangle can be scalene.......
Some equilateral triangles are not isosceles?
All isosceles triangles are not equilateral triangles
True or false all isosceles triangles are also equilateral triangles?
False.
Is All isosceles triangles are similar true or false?
false
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.
True are false are all equilateral triangles are isosceles?
False. Equilateral triangles are equilateral. All isosceles triangles have two of the sides the same, with the hypotenuse being longer than the other two.
True or false All equilateral triangles are also isosceles triangles?
True
Can an angle be both obtuse and isosceles true or false?
False
Isosceles triangles may be obtuse or acute but never right?
false
Is it true or false that isosceles triangles have 2 equal sides?
True
Isosceles triangles can be acute or obtuse true or false?
true
Is it true or false that an isosceles triangle may have a right angle?
It is true.
All equilateral triangles are also isosceles triangles?
True or False, depending on your definition of isosceles triangles!Actually, whether your answer is true or false depends upon your definition of an isosceles triangle. Some mathematicians define an isosceles triangle as one with at least two sides, while others define an isosceles triangle as one with exactly two sides. The latter definition is the more generally accepted one. Since an equilateral triangle has three, not exactly two congruent sides, people using the second definition of isosceles triangles would say that the statement is false, not true.False because an equilateral triangle has 3 equal sides whereas an isosceles triangle has only 2 equal sides
