No. The only requirement for a triangle to be a 45-45-90 triangle is for it to have at least two congruent sides/angles. The measure of the two congruent angles can be anything.

Is right triangles with 2 congruent legs is always a 454590 triangle?
Yes if you mean in degrees
Is a right triangle always an isosceles triangle?
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
Can you show me a triangle with only one line of symmetry?
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
A triangle with two congruent sides is always?
An isosceles triangle.
Is an isosceles triangle sometimes an equilateral triangle?
sometimes, but not always
A triangle that has angles that measures 454590 degree is a?
A 45-45-90degree triangle is classified as an isosceles triangle.
Is right triangles with 2 congruent legs is always a 454590 triangle?
Yes if you mean in degrees
Is a right triangle always an isosceles triangle?
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
Is an isosceles triangle always an acute triangle?
no
Is a scalene always isosceles?
No. A scalene triangle is never isosceles. An isosceles triangle has two equal sides. A scalene triangle has none.
Is an isosceles triangle always obtuse?
No not always
Can you show me a triangle with only one line of symmetry?
An Isosceles triangle has at least one line of symmetry but if it has more than one line of symmetry it can be an Equilateral triangle as well as a Isosceles Triangle. So a triangle with one line of symmetry is always Isosceles and If it has more than one it is always an Equilateral triangle as well as an Isosceles triangle. Example of an Isosceles triangle:
An equilateral triangle is always an isosceles triangle?
Yes.
If a triangle is obtuse then it is always isosceles?
No
A triangle with two congruent sides is always?
An isosceles triangle.
Is an isosceles triangle sometimes an equilateral triangle?
sometimes, but not always
Does an isosceles triangle have a right angle?
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
