5 free geometry resources for Year 9: 3 worksheets, 2 study guides. Answers included.
Shapes, angles, transformations and trigonometry. In Year 9, Year 9 students solve more complex equations, work with linear graphs, meet Pythagoras' theorem and trigonometry, and expand binomials.
Students will practise: understanding the relationship c[sup 2] = a[sup 2] + b[sup 2] in a right-angled triangle; identifying the hypotenuse; finding the hypotenuse and a shorter side; testing whether a triangle is right-angled; understanding how to label the hypotenuse, opposite and adjacent sides relative to an angle; choosing the correct trigonometric ratio from the sides involved; finding an unknown side length in a right-angled triangle; finding an unknown angle using inverse sine, cosine and tangent.
