Question

A triangle having sides of 2, 2, and 3 contains _____.

Answer 1

Don't quote me but i'm pretty sure it is a right triangle 

Answer 2

Answer with explanation:

It is given that the triangle has three sides having  side length 2, 2 and 3 units.

Since two sides of triangle is equal, So it is an Isosceles triangle.

To check whether it has any of the angle is right angle or Obtuse angle, we will use Cosine formula.

Since Angle Opposite to Larger side is greater.Angle Opposite to Larger side 3 units be m°.

$\cos m=\frac{2^2+2^2-3^2}{2\times2 \times 2}\\\\\cs m=\frac{4+4-9}{8}\\\\ \cos m=\frac{-1}{8}$

⇒→Since , cosine of angle between  two sides ,2 and 2 is , Negative.It means it is an Obtuse Angle.

So, other two angles will be acute.

So, the given triangle having sides 2,2,and 3 is Obtuse Isosceles Triangle.
