at the vertex i think
a triangle with two sides the same length and no 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.
...the remaining two sides?
A right triangle, by definition, has a right (or 90o) angle. The side that is opposite that right angle is the hypotenuse. That is to say, the other two sides, which are not the hypotenuse, are the two sides which meet at a right angle.
Not actually sides. Angles do not have sides, they have legs. All angle have two legs.
You use the points of the vertex and on the two sides. For example a right angle with a vertex of A and two sides B and C. would be Angle BAC
The two sides are called base and height and the sloping part of the right angle triangle is called the hypotenuse.
The dimensions of any right angle triangle other than an isosceles right triangle which has two equal sides.
Other than the diagonal side of the right triangle, the other two sides make a perpendicular right angle triangle. The right angle is 90 degrees
The right angle is formed by the intersection of the triangle's "legs".
A right angle.
The two shorter sides are the legs.
