A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
Classifications by side length or comparison of angles and sides:scalene - no sides or angles equalisosceles - two sides and angles equal (congruent)equilateral - all sides and angles equal (all 60° angles)Classifications by included angles :right triangle - contains a 90° angle (right angle)oblique triangle - has no right angleacute triangle - contains all angles less than 90°obtuse triangle - contains one angle greater than 90°

A right triangle is a special case of either a scalene or isosceles triangle.
Yes, they are.
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
SAS
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, then the two triangles are congruent.
The Angle Side Angle postulate( ASA) states that if two angles and the included angle of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.

Yes, they are.
In a right triangle, two of the angles are acute ones. Referring to one of the acute angles, the ratio of the side opposite it to the side adjacent to it is the tangent of the angle.
