Question

abc is a right angular triangle where angle a is 90degree and ab is equal to bc find angle b and angle c

Answer 1

as abc is a triangle so sum of its all angle is 180 degree 

as the triangle has a angle as 90 degree so , rest of remaining angle sum is 180-90=40
as ab and bc are equal so angle b and angle c are 45 degree as {angle subtended by equal sides are equal}

HOPE THIS HELPED U

Answer 2

this triangle is not possible.. ab =bc .. tht means <a=<c .. but <a is 90° therefore.. <c=90°
...and there cant be two 90° ..
sides wont intersect coz the are parallel.. Nd no triangle would be formed
