This math test covers similarity in plane figures and using it to solve problems. It contains 3 questions: 1) Find the length of side QR if rectangle ABCD is similar to PQRS and one side is 6 cm. 2) Find the lengths of sides ML, PQ, and PR if triangles KLM and PQR are similar. 3) Find the lengths of sides AB, AD, AE and the area of trapezoid NOPQ if the two trapezoids are similar.

2. 1. Suppose that ABCD rectangle similar
with PQRS rectangle
• so find the length of QR
6 cm

3. 2. KLM similar with PQR and then
find length of: a) ML b) PQ c) PR

4. 3. Suppose that Two trapezoids are
similar like below figures, find length
of: a) AB b)AD c) AE d)area of NOPQ
