Answer 2

Answer:

Every triangle has at least two acute angles.

Step-by-step explanation:

Every triangle has at least two acute angle.

To proved this,

$\large\bf\red{Acute\; angle}$

Acute angle is a angle which has less than 90° measure.

Let's take one example for understand it more perfectly.

Let's take one right angle triangle (see in the attachment)

△ABC is an right angle triangle.

∠A = 45°

∠B = 90°

∠C = 45°

we now that every triangle has 180° measure.

∴ △ABC = 180°

∴ △ABC = ∠A + ∠B + ∠C = 180°

∴ △ABC = 45° + 90° + 45° = 180°

We know that acute angle has measure less than 90°

Here, ∠A and ∠C has measure less than 90°

Hence proved.
