  6. An right-angled triangle has one line of symmetry

  7. The hypotenuse is always opposite the right angle

  8. The sloping side is the hypotenuse

  9. Right-angled triangles have two equal sides

  10. Double the lengths of the triangle’s sides = double the size of the angles

  11. The area of a triangle can be found using the formula .
