a 90 degree, improve this answer if you need to, im fine with it....
Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!
A right angle triangle
Not normally because an apex angle is found on an isosceles triangle.
The hypotenuse is the longest side in a right triangle and it is opposite the right angle. It is always opposite the right angle and is found by using the Pythagorean theorem.
An interior angle is any angle on the interior of the triangle.
A triangle if not found congruent by CPCTC as CPCTC only applies to triangles proven to be congruent. If triangle ABC is congruent to triangle DEF because they have the same side lengths (SSS) then we know Angle ABC (angle B) is congruent to Angle DEF (Angle E)
If you mean cosine then it is angle ratio found in a right angle triangle which is adjacent/hypotenuse
The hypotenuse

A right angle triangle.
ABC angle is an angle,not a triangle!
Types of triangle ; EQUILATERAL all three sides the same length and all three angles are 60 degrees. ISOSCELES Two sides the same length and two angles have the same degrees value. RIGHT-ANGLED All three sides can be of different lengths. However, it MUST have one Right-Angle (90 degrees) SCALENE All three sides of different lengths and all three angles of different angular values. NB In ALL four cases the sum of the interior angles MUST ADD TO 180 DEGREES.

The hypotenuse is the longest side in a right triangle and it is opposite the right angle. It is always opposite the right angle and is found by using the Pythagorean theorem.
The 3rd side of the right angle triangle can be found by using Pythagoras' theorem.
