Four sided
Square:
Angles ABC=BCD=CDA=DAB=90 degrees, futhermore lenght of a=b=c=d and sides a||c b||d.
Rectangle:
Angles ABC=BCD=CDA=DAB=90 degrees, futhermore lenght of a=c, b=d and sides a||c b||d.
Parallelagram:
Angles ABC=CDA but not=90 degrees, BCD=DAB but not=90, and lenght a=c,b=d, and sides a||c b||d.
Triangles:
Equilateral:
Angles ABC=BCA=CAB=60 degrees, and lenght of sides a=b=c.
Isosceles:
Angles ABC=BCA but not = CAB and lenght of a=b but not equal c.
Scalene:
Angles ABC not equal BCA and not equal CAB, and lenght of sides a not equal side b and not equal side c.
Right Angle:
Angle ABC=90 degrees and SIN CAB = ratio of c:a, COS CAB = ratio b:a and TAN CAB = ratio c:b.
