Trigonometry in Right Angled Triangles

Labelling Right Angled Triangles WORKSHEET

Suitable for Year groups: Year 9, Year 10, Year 11
GCSE Tier: Foundation/Higher
Targeting grades: 4-5
Prerequisite knowledge: Right angles.
Learning Objective: Use trigonometric ratios in similar triangles to solve problems involving right-angled triangles.

Labelling Right Angled Triangles WORKSHEET DESCRIPTION

This worksheet helps students master the skill of labelling sides of right-angled triangles, an essential foundation for trigonometry.

Firstly pupils are asked to label the sides relative to the angle θ as opposite, adjacent, or hypotenuse.

Next learners ensure six triangles are fully labelled, including adding a label of θ for the included angle, when given one side labelled already.

Then students will find and label right-angled triangles within shapes using a given angle, θ. Shapes include: a rectangle, trapezia, isosceles triangles, and a parallelogram.

All worksheets are created by the team of experienced teachers at Cazoom Maths.
