Question

8.Each acute angle of a right angled isosceles triangle is​

Answer 1

Answer:

45°

Step-by-step explanation:

In a right angled isosceles triangle,

One angle will be of 90° as it is a right angled ∆.

And the another two angles will be equal as it is an isosceles triangle.

So, using angle sum property of a triangle,

Angle 1 + Angle 2 +Angle 3 = 180°

90°+ 2×Angle 3 = 180° (Bcoz angle 2 = angle 3)

2×angle 3 = 90°

angle 3 = 45°

Also, angle 2 = 45° ( as angle 2 = angle 3)

Answer 2

Answer:

Each acute angle=45°

Step-by-step explanation:

Let the acute angles are x and x

and the third one is 90°

so x+x+90=180

2x=180-90=90

x=90/2=45°

Each acute angle=45°
