ملخص الدرس

This lesson introduces Pythagoras' theorem, which relates the sides of a right-angled triangle: the square of the hypotenuse is equal to the sum of the squares of the other two sides. It covers using the theorem to find the length of a side, and its converse to determine if a triangle is right-angled. The lesson also includes classifying triangles as acute, right, or obtuse using Pythagoras' inequality, and solving real-life problems.

هتتعلم إيه فى الدرس ده

• In a right-angled triangle, c² = a² + b², where c is the hypotenuse.
• The converse: If a² + b² = c², then the triangle is right-angled.
• Pythagoras' inequality: If c² < a² + b², the triangle is acute; if c² > a² + b², it is obtuse.
• Common Pythagorean triples include (3,4,5), (5,12,13), (8,15,17), etc.
