Yes, a right triangle has only one set of perpendicular lines.
The mode, I think is not always a number in the data set it represents, for example I have a set of numbers, 1,7,2,4,6. You'll put them in order; 1,2,4,6,7. And there is no number that is the mode. So, I believe that is correct.
No because the given sides do not comply with Pythagoras' theorem for a right angle triangle.
A 90 degree angle and 2 acute angles will form a right angle triangle.
n ∑(f(x)/n) x = 0 Where f(x) represents the xth element in the set you're averaging, and n represents the number of elements in that set.
They are Pythagorean triples
Yes, a right triangle has only one set of perpendicular lines.
No. Triangle numbers are a fixed set of numbers that can't be altered to make one certain number turn into a triangle number.
If they are a Pythagorean triple then they will form a right angle triangle

There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
The median.
