Answer:

a right triangle cannot have an obtuse anqle

Step-by-step explanation:

just visualise a right triangle in your head and try to put an angle greater than 90degree into it..... you wont be able to do it without making in a scalene triangle instead of right angled.

now for a practical explanation,

we know that the sum of the three angles of a triangle = 180 degree

so let A, B and C be the three angles

then A+B+C= 180 --------- equ (1)

now in a right triangle one of the angles need to be 90

so lets take that 90 degree angle as C

then equ (1) becomes

A+B+C = A+B+90=180

so A+B= 180-90=90

if A+B has to be 90 and both angles are ofcourse positive

then there is no case where either A or B is obtuse

so A is acute

B is acute

C is right angled

so NO OBTUSE ANGLE

hope it helps,........
