Question

in a right angle isosceles triangle what is the measure of each equal angle?​

Answer 1

The sum of internal angles of triangle=180 degree
In isosceles triangle=two equal angles are present
Let the equal angle =x
=>x+x+90=180
2x=90
=>x=45
So each equal angle is 45 degree

Answer 2

Answer:

each equal angle is 45

Step-by-step explanation:

let each equal angle be "a" and "b"

let remaining angle be "c"

a+b+c=180–<1>(angle sum property)

But a=b,

So substitute b=a in–<1>

a+a+c=180

2a+c=180

2a=180-c

a=180-c/2

As it is a right angled triangle one Angle is 90

So "c"=90 as a or b cannot be 90

a=180-c/2

Put c=90

a=180-90/2

a=90/2

a=45

As a=b

45=b
