Similar Shapes!
- What the buns is this?
- Similar Shapes are identical in
shape (obviously), but not in size.
- For example, two circles
are similar, and two
squares are similar...
- Two rectangles could be similar...
but probably won't be...

- Stuff to remember!
- For any pair of similar
figures corresponding sides
are in the same ratio and
corresponding angles are
equal.
- Similar Figures
- Here, B is an enlargement of A. The
lengths have doubled, but the angles
have stayed the same.

- Yayu! Questions! :' )
- The rectangles pqrs and PQRS are similar. What
is the length of PS?
- LOL do you give up? ¬ u ¬
- The answer is PS = 15.75cm
Here's how to work it out.
- We know that the sides are in the same ratio, so
PS/ps = PQ/pq
- Include the numbers you already know from
the diagram like this: PS/9 = 7/4
- PS = (7 × 9) ÷ 4 = 63 ÷ 4 = 15.75 cm
- Remember : Try to use
the formula which has
the 'unknown' at the top
of the fraction.
