A triangle with a right angle is a right triangle.
An isosceles right triangle.
Then its not a triangle.
no
No that would be impossible but it can have 2 acute angles and 1 right angle which would be a right angle triangle

Right triangle.
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
An isosceles right triangle.
Then its not a triangle.
no
It is an isosceles right angle triangle
No that would be impossible but it can have 2 acute angles and 1 right angle which would be a right angle triangle
1/2*base of triangle*height(the perpendicular)=Area of right angled triangle
