Question

8- Prove that a triangle must have atleast two acute
angles.
​

Answer 1

Step-by-step explanation:

The sum of the measures of all the angles of a triangle..

=60+60+60 (degree)

=180 degree...

Suppose , 50 +40+90 =180

Here , the 2 angles are acute angles...

Again ...

110+30+40=180 ...

It's also a triangle...

Here , the two angles are acute...

Therefore , in a triangle at least 2 angles must be acute...

Hope, it would be correct...
