An acute triangle can be an isosceles triangle, but it doesn't have to be. An isosceles triangle can be an acute triangle, but it doesn't have to be.
A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.
yes a scalene triangle is a isosceles triangle.* * * * *No. A scalene triangle is not an isosceles triangle. The sides of a scalene triangle must all be of different lengths. In an isosceles triangle two of the sides must be the same length. If all three sides are different (scalene) then two cannot be the same (isosceles).
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
it is irregularIt is irregular although it has two equal sides
Asymmetrical. The answer is NOT irregular. An irregular shape, such as an isosceles triangle does have an axis of symmetry.
It is irregular as not all the sides have the same length.
It can be. For example a square with an isosceles triangle of top has a bilateral symmetry.
An isosceles triangle and an irregular pentagon or two trapeziums.
An acute triangle can be an isosceles triangle, but it doesn't have to be. An isosceles triangle can be an acute triangle, but it doesn't have to be.
isosceles triangle
Strictly speaking it is an irregular polygon because all of its 3 sides are not equal because it has only two equal sides.
A right triangle and an isosceles triangle have the fact that they are both triangles in common. A right triangle can also be an isosceles triangle.
something with eight or more sides* * * * * An irregular polygon is one with either two (or more) sides that are unequal or two (or more) angles that are unequal. So an isosceles triangle, for example, is irregular.
An isosceles triangle is a triangle that has two equal sides.
Are isosceles triangle sometimes an equilateral triangle
