A polgen with three sides is a triangle.
It has three sides, three angles and three vertices.
We classify triangles according to the sides and angle measures
A triangle with all three sides equal is called an equilateral triangle
A triangle with two sides equal is called an isosceles triangle.
A triangle with no sides equal is called a scalene triangle.

Classification of triangles according to the measure of their angles.
A triangle in which all three angles are acute (less than 90°) is called an acute triangle.
A triangle in which one angle is a right angle is called a right triangle.
A triangle in which one angle is obtuse is called an obtuse triangle

Step-by-step explanation:
A polygon having three sides is considered a triangle. Hence, the sum of the angles will be equal to 180
o
. ACQ, that the two angles are 15
o
and 60
o
Let y will be the third angle of the triangle.
⇒ 15
o
+60
o
+∠y=180
o
⇒ ∠y=180
o
−75
o
⇒ ∠y=105
o
Therefore, it is an obtuse angled triangle because one of the angles is obtuse
