Types Of Trapezoid / Trapezium
Types Of Trapezoid Based On Sides:
- Scalene Trapezoid / Irregular Quadrilateral ( No sides equal and no internal angles are the same ).
- Isosceles Trapezoid ( Two non-parallel sides are equal in length, two sides are parallel ).
Types Of Trapezoid Based On Angles:
- Acute Trapezoid : two adjacent angles acute ( < 900 ).
- Obtuse / Oblique Trapezoid : two opposite angles obtuse ( > 900 ).
- Right Trapezoid : two adjacent right angles ( 900 ).
Types Of Triangle
Types Of Triangle By Lengths Of Sides:
- Equilateral Triangle : all sides are equal and all angles are equal.
- Isosceles Triangle : two sides are equal.
- Scalene Triangle / Irregular Triangle : no sides are equal.
Types Of Triangle By Internal Angles:
- Right (Angle Of) Triangle : one right angle ( 900 ).
- Isosceles Right Triangle.
- Scalene Right Triangle.
- Acute (Angle Of) Triangle : all angles acute ( < 900 ).
- Oblique / Obtuse (Angle Of) Triangle : one angle obtuse/oblique ( > 900 ).

Types Of Quadrilaterals
Types Of Quadrilaterals ( 4 sides shape / 4 sided polygon ):
- Rectangle : Opposite sides are equal, four internal right angles.
- Parallelogram : Opposite sides are equal and parallel, opposite interior angles are equal.
- Square : All four sides are equal, four internal right angles.
- Rhombus : quadrilaterals whose four sides are all equal in length.
- Trapezoid/Trapezium : One pair of opposite sides is parallel.
- Kite : Two pairs of adjacent sides are equal, one pair of opposite interior angles are equal.
- Diamond : made up of two equilateral triangles.
