All Triangles add up to 180 degrees, no matter if it is Right or Scalene or ANY TRIANGLE!! If it does not, it is not a triangle!
A right angle triangle has 2 acute angles that add up to 90 degrees, along with 1 right angle of 90 degrees.
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
there are eight right angled triangles

Depends on the type of triangle. A right-angled triangle has ONE right angle - the remaining two angles total 90 degrees.
A scalene triangle is a 80 triangle,in rare casses it can be 90 degrees.
A right triangle has only one right angle (a 90 degree angle), by definition. The sum of the other two angles equals 90 degrees, so the sum of all three angles is 180 degrees. Every triangle, right triangle or not, has three angles whose sum is 180 degrees.A right angle triangle has only 1 right angle which measures 90 degrees
