This is an acute scalene triangle
The triangle is acute since all three angles (58, 57, 65) are less than 90 degrees
The triangle is scalene as the angles are all different. So this leads to the sides being different lengths. No two sides are the same length.
Perpendicular lines, when intersecting, will always create a right angle at the intersection point. A right angle is an angle that is exactly 90 degrees.
