Question

If the angles of a triangle are in the ratio 1:1:2, then it is ​

Answer 1

Answer:

Correct option is A)

Let the angles are x

1

,x&2x

then x+x+2x=180

∘

(by angle sum property )

x+x+2x=180

∘

⇒4x=180

∘

⇒x=

4

180

∘

=45

∘

⇒x=45

∘

So , angles of triangle are 45

∘

,45

∘

&90

∘

.therefore . it is an isosceles right angled triangle

Answer 2

Answer:

let angles of the triangle be 1x, 1x, 2x

= 1x + 1x + 2x = 180 degree

= 4x = 180 degree

= x = 180 ÷ 4

= x = 45 degree

therefore, the angles of a triangle are 1x = 1×45 = 45 degree

1x = 1×45 degree = 45 degree

2x = 2×45 degree = 90 degree.

hence, it is a right angled triangle.
