No because the given dimensions do not comply with Pythagoras' theorem for a right angle triangle.
A triangle has three angles and three sides and it is possible for all three angles to be different from each other. Each angle is defined by two of the sides - which form the rays meeting at the angle's vertex. The third side is the "opposite" side. The above statement can be proven (eg by the sine rule) for any triangle.

A 90 degree angle and 2 acute angles will form a right angle triangle.
The right angle is formed by the intersection of the triangle's "legs".
If they are a Pythagorean triple then they will form a right angle triangle
No because the given dimensions do not comply with Pythagoras' theorem for a right angle triangle.
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.

They are the "legs" of the triangle.
The 3rd angle is 70 degrees which would form a right angle triangle.

If you mean 5 by 12 by 13 then they will form a right angle triangle
I think the rule you're mis-stating it that the sum of the 3 internal angle measurements of a triangle will always add up to 180 degrees. Think about it, if you cut the ends off of any triangle and set them next to each other like a fan the points combine to form a straight line.
anything over 180, A triangle is composed of 180 degrees, so if one angle alone is 180 degress then the shape is not A triangle.
