Types of triangles
|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°.|

|SSS(side, side, side)||△ABC≡△EDF△ABC≡△EDF|
|SAS(side, incl. angle, side)||△GHI≡△JKL△GHI≡△JKL|
|AAS(angle, angle, side)||△MNO≡△PQR△MNO≡△PQR|
|RHS(9090°, hypotenuse, side)||△STU≡△VWX△STU≡△VWX|
