Question

every triangle has atleast how many acute angles?​

Answer 1

Answer:

two angles

Step-by-step explanation:

At least two angles of any triangle are acute angles. In a 180˚angle, if one angle is obtuse (more than 90˚), the other will always be an acute angle (less than 90˚).

Answer 2

Answer:

At least 2 acute angles.

Step-by-step explanation:

The sum of all angles of a triangle is 180 degrees.

You know that all acute angled triangles have all acute angles.

Let's take a case of a right angled triangle.

You have a right angle there which is 90.

You need another 90 degrees to make it 180 degrees.

You will always require two acute angles to make it 90.

Let's take a case of an obtuse angled triangle.

You have an obtuse angle here, say 120 degrees.

Now to make it 180 degrees you need another 60 degrees.

This will be possible if you take two acute angles.

Like in this example you can take 20 and 40 to make 60 degrees.

Hope it helps !
