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.
