A triangle with a right angle and different lengths for sides is a right, scalene triangle.
A rectangle has four sides whereas a right angle triangle has only three sides.
No. Given a triangle with only the right angle and the hypotenuse, you cannot calculate the other sides nor the other angles.
Adjacent means next to. So you're asking what sides of a triangle are next to the right angle of a triangle. That would be the 2 shorter sides of the triangle or 'legs' of the triangle. The hypotenuse (which is the longest side of the triangle) is directly across from the right angle.
It is an isosceles right angle triangle that has two equal sides which has two 45 degree angles and a 90 degree angle.
