SAS stands for "side, angle, side" and means that we have two triangles where:
- the ratio between two sides is the same as the ratio between another two sides
- the angles betweet this sides are equal.
We have m∠U = m∠ R.
The ratio:
[tex]12:18=\dfrac{12}{18}=\dfrac{12:6}{18:6}=\dfrac{2}{3}\\\\10:15=\dfrac{10}{15}=\dfrac{10:5}{15:5}=\dfrac{2}{3}[/tex]
Answer: The triangles are similar.
