1)Acute angled triangle - All the angles are acute angle

2)Right angled triangle - 1 angle is right angle

3)Obtuse angled triangle - 1 angle is obtuse angle

2)Isosceles triangle - Only 2 sides are equal and angles opposite to the equal sides are equal

3)Scalene triangle - No Sides are equal

1) Trapezium - Diagonals intersect each other.

Line joining the midpoints of the non parallel sides is parallel to either of th two parallel sides .

2) Parallelogram [ Square , Rectangle and Rhombus come under parallelogram] - Opposite sides and angles are equal .

Diagonals of a parallelogram bisect each other .

3) Kite - Has 2 pairs of adjacent sides equal .

__Based on Angles :__1)Acute angled triangle - All the angles are acute angle
