Question

Prove that a triangle has two acute angle

Answer 1

Step-by-step explanation:

A triangle should have two acute angles and an obtuse angle or right angle to form a triangle. A triangle cannot have two right angles because both the angles will together form 180° and they will not form a triangle. Even, it cannot consist of two obtuse angles

Answer 2

Answer:

$\huge\sf\bold\blue{Answer}$

According to Angle sum property Any triangle have a measure of 180⁰

In the case of $\bold{Acute\: angle\: triangle}$

We have all the angle under $\angle{90⁰}$ to make it a acute angle

In the case of $\bold{Obtuse\: angle\: triangle}$

These angle are between $\angle{90⁰}$ to $\angle{180⁰}$

So we know that sum cant be more than 180⁰ then two angle can't be more than 90⁰ so two acute angle are required and this verifes in the right angled triangle's case also
