Answer:
Every triangle has at least two acute angles.
Step-by-step explanation:
Every triangle has at least two acute angle.
To proved this,
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.
