No, only one is and it is known as a 'right isosceles triangle'. By definition an isosceles triangle has two equal sides and two equal angles. If those two equal angles are 45o then the third angle must be 90o.
no
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
they are all triangles
isosceles are 45-45-90
Yes.
no
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
All isosceles triangles are not equilateral triangles
No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.
The right isosceles triangle has 180 degrees as all triangles do
All isosceles triangles are not equilateral triangles
An isosceles triangle may have a right angle, but a right angle is not a requirement of all isosceles triangles.
It can only have a maximum of one- and that is only if it is a right-angled isosceles triangle. ----------------------------------------------------- Yes not all isosceles triangles are right angle triangles - this is a special case.
