0.5ml equals how many L? 0.005 or 0.0005?

Question

which statement is true?
a scalene triangle may also be an equilateral triangle
an obtuse triangle may have a right angle
an equilateral triangle is always an acute triangle
an isosceles triangle always has an obtuse angle?

Answer 1

.0005 L
Equilateral triange is always acute.

Answer 2

0.5 ml = 0.0005 L

Assuming Euclidean geometry (flat space):
All triangles have the following property:
The sum of thier angles is 180 degrees.

An obtuse angle is an angle greater than 90 degrees.

An obtuse triangle by definition has one angle greater than 90 degrees, therefore, the other two angles added together must sum to less than 90 degrees, therfore they must each be less than 90 degrees, therefore an obtuse triangle may NOT be a right triangle.

An equilateral triangle by definition has three equal angles. Since these angles must sum to 180 degrees, each of them must be one-third of 180 degrees, or 60 degrees, which is less than 90 degrees, which means an equilateral triangle IS an acute triangle.

Yes, a scalene triangle may be an equilateral triangle.

An equilateral triangle is also an isosceles triangle. Since an equilateral triangle does not have an obtuse angle, this means that isosceles triangles do NOT always have an obtuse angle.

Answer 3

0.5ml=0.0005L
The 3rd one is rite -an equilateral triangle is always an acute triangle

Answer 4

0.0005 L = 0.5 mL.

Answer 5

The 3rd statement is right and

0.5ml = 0.0005 l.........................
