ملخص الدرس

This lesson covers quadrilaterals, starting with the concept that their interior angles sum to 360°. It then details the special types of quadrilaterals: trapezium, parallelogram, rectangle, rhombus, and square, listing their specific properties. The lesson explains the hierarchy (family tree) of these shapes and how to prove a quadrilateral is a parallelogram. It also shows how to use these properties to set up and solve equations for unknown values.

هتتعلم إيه فى الدرس ده

• A quadrilateral is a polygon with four sides, and its interior angles always sum to 360°.
• A parallelogram is a quadrilateral with both pairs of opposite sides parallel. Special types include rectangles, rhombuses, and squares.
• A rectangle has right angles and equal diagonals; a rhombus has equal sides and perpendicular diagonals; a square has the properties of both a rectangle and a rhombus.
• The properties of quadrilaterals are used to set up equations and solve for unknown angles and lengths.
