Question

the measure of sacute angle of an isosceles right angled triangled is​

Answer 1

Answer:

Let triangle ABC is right angled isosceles triangle right angle at A.

so AB = AC.

therefore, <BCA = <CBA = x (say)

Using angle sum property

90 + x + x = 180

2x = 90

x = 45.

so each acute angle is 45

Answer 2

Answer:

Let triangle ABC is right angled isosceles triangle right angled at A

so AB=AC

Using angle sum property

90+x+x =180

2x=90

so x=90÷2=45
