Question

can a triangle have two right angles why​

Answer 1

no, any triangle can't have two right angles

bcoz

sum of three angles of a triangle= 180°

but in this case

sum of two angles= 180

it means the third angle = 0°

which is not possible

hope it will help you.....

Answer 2

no. because a triangle has three angles and thier sum =180 but if two angles measures sum =180 then 3rd angle will be 0 but then it not be a triangle
