17 cm because it's an equilateral triangle
An isosceles right angle triangle
Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.
Well, it doesn't exactly have "an angle that measures 45 and 90 degrees". It has one angle that measures 45 degrees, and another angle that measures 90 degrees. That's an isosceles right triangle. The third angle is also 45 degrees, and the length of each leg is 70.7% of the length of the hypotenuse. .
An angle of a triangle can have any value between 0 and 180 degrees.
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.

In order to find length BC the length of AC or length of the hypotenuse must be given
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
A right triangle is a triangle that contains a 90 degree angle, an obtuse triangle contains an angle that is from 91 degrees to 179 degrees.
It depends upon the length of the sides.
An isosceles triangle is a triangle that has two sides of equal length. A right triangle has an interior angle of 90 degrees. A right isosceles triangle has both characteristics. The 90 degree angle will be the angle formed by the sides of equal length.
All you can say is that the length of the third side will be positive and less than double the length of either of the equal sides. You need to know at least one angle. If that angle is less than 90 degrees (unless it is 60 degrees), you need to know whether it is the angle between the two equal sides or between one of them and the third. [If the angle is 60 degrees then the triangle is equilateral and the third side is the same as the other two.]
An obtuse angle is an angle measuring between 90 and 180 degrees
