Question

can a triangle have each angle equal to 90 degree?​

Answer 1

noo.. a triangle should have minimum 3 sides. if all angles are 90 degrees, it cannot form a closed figure with 3 sides. hence it cannot be possible

Answer 2

Step-by-step explanation:

an right triangle has one angle equal to 90 degrees. A right triangle can also be an isosceles triangle--which means that it has two sides that are equal. A right isosceles triangle has a 90-degree angle and two 45-degree angles. This is the only right triangle that is an isosceles triangle.
