Question

if ∆ABC, angle B = 90 if length of AB=1 cm and BC= 1 cm then angle A is​

Answer 1

Given that,

B=90⁰

AB=1cm

BC=1cm

as the given question says that the given triangle is a isosceles right angle triangle

in any isosceles right angle triangle the three angles will be 90⁰,45⁰,45⁰.

So the angle A is 45⁰
