Types of triangles 

Name	Diagram	Properties
Scalene		All sides and angles are different.
Isosceles		Two sides are equal in length. The angles opposite the equal sides are also equal.
Equilateral		All three sides are equal in length and all three angles are equal.
Acute-angled		Each of the three interior angles is less than 9090°.
Obtuse-angled		One interior angle is greater than 9090°.
Right-angled		One interior angle is 9090°.
