Question

Prove that a triangle cannot have more than one right angle

Answer 1

it is not possible as the angle sum property of triangle prove that sum of all sides 180 then what about third side?

Answer 2

They must both be less than 90 degree and so must be acute. Triangle cannot have more than one obtuse angle because there are three sides and if u add three sides it will become 180 degree and obtuse angle is greayer than 90 degree and the other two has to be less than 90 degree.
