Similar Triangles (B) WORKSHEET
Similar Triangles (B) WORKSHEET DESCRIPTION
Work with similar compound triangles in Similar Triangles (B). Here students will prove triangles are similar as well as calculate missing lengths in similar triangles.
In section A, learners will prove that three pairs of triangles are similar by using angle in parallel line rules and considering the ratio of corresponding lengths to find the condition for similarity.
Next, students calculate missing lengths in similar triangles. Questions consist of triangles within triangles and vertically opposite triangles.
Challenge your pupils with section C, made up of two questions where students may want to use algebra to find three missing lengths.
All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions
Students should be comfortable with angles in parallel lines, as these rules are essential for proving triangle similarity in the first section. They'll also need to understand the conditions for similarity and be able to use scale factors to calculate missing lengths in similar shapes, since these skills underpin both the proof work and the length calculations throughout the worksheet.
