If you mean angles then it is a right angle triangle or an isosceles right angle triangle
A right triangle. Also an isosceles triangle.
You can measure it with a ruler.
Yes in a 90 45 45 triangle
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
is it a right triangle if the measure is 5 7 and 9
