  1. Geometrical Figures Present to M.Veerasakdi By: Name SarunThienpaitoonClass: 4/4 No. 12

  2. Geometrical Figures

  3. 4-sided figures Rectangle All angles are right angles. Opposite sides are parallel. Opposite sides are equal. B C AB = CD, AD = BC AB // CD, AD // BC A D

  4. 4-sided figures Square All angles are right angles. Opposite sides are parallel. All sides are equal. P S PQ = QR = RS = PS Q R

  5. 4-sided figures Parallelogram Opposite sides are parallel. Opposite sides are equal. K N KL = MN,KN = LM KL // MN,KN // LM L M

  6. 4-sided figures Rhombus Opposite sides are parallel. All sides are equal. A D AB = BC = CD = AD AB // CD, BC // AD B C

  7. 4-sided figures Trapezium A trapezium is a four sided closed figure. It has only one pair of opposite side parallel. P S PS // QR R Q

  8. Property of a triangle B 2.5cm 2.cm A C 2.5cm

  9. Types of triangles Right-angled triangle A triangle with one right angle is called a right-angled triangle. The right angle is often marked as shown.

  10. Types of triangles Obtuse-angled triangle A triangle with one obtuse angle is called an obtuse-angled triangle.

  11. Types of triangles Acute-angled triangle A triangle with all three angles acute is called an acute-angled triangle.

  12. Types of triangles Equilateral triangle A triangle with its three sides equal is called an equilateral triangle. It also has three equal angles.

  13. Types of triangles Isosceles triangle A triangle with two equal sides is called an isosceles triangle. It has two equal angles.

  14. Types of triangles Scalene triangle A triangle having all sides of different length is a scalene triangle.
