Two slides make one
Can two slides in a row be done as one slide?
Today you'll discover
- how to add slides that go the same way
- what happens when slides go opposite ways
Think firstTwo slides: 4 right, 3 up, then 5 right, 2 up
What one slide does the same as both slides together?
Decide first, then press Next. Keep across with across and up with up.
A coordinate grid with A at (2, 3), B at (6, 6) and C at (11, 8). Arrows show A sliding 4 right and 3 up to B, then B sliding 5 right and 2 up to C. Then a single L-shaped arrow goes from A straight to C: 9 right, 5 up.
