isosceles right triangle or the 45 45 right triangle
Left triangle.
It is a right angled isosceles triangle.
45 degrees is an angle, not a triangle.A triangle containing an angle of 45 degrees can be any kind of triangle except an equilateral triangle.
A right triangle. Also an isosceles triangle.
isosceles right triangle or the 45 45 right triangle
An isosceles triangle can never be an equilateral triangle because only 2 of its 3 sides are equal in lenght whereas an equilateral triangle has all 3 of its sides equal in length. But an isosceles triangle can take the shape of a right angle triangle whose interior angles are 90, 45 and 45 degrees.
if the triangle was an equilateral triangle, you would have been able to just multiply 45 with 3... but if the triangle was some other kind of triangle, you would have to know the other sides
No because an isosceles triangle has various two congruent angles. A 45-45-90 triangle is technically an isosceles triangle.
Isosceles triangle
A triangle with a 90 and two 45 degree angles is an isosceles right angle triangle.

Not normally but if it has angles of 90, 45 and 45 degrees it is then both a right angle and an isosceles triangle
A 45-45-90degree triangle is classified as an isosceles triangle.
A right triangle. Also an isosceles triangle.
