The question
Two triangles of very different sizes, at the same angle. Why do they give the same number?
Think about it
Layla builds a ramp 3 metres long. Omar builds one 6 metres long.
Both ramps rise at the same angle from the ground.
What number about a ramp stays the same when the ramp gets bigger?
