👉 Drag the solid corners! The shape will automatically adjust to remain a parallelogram.
🔍 Investigation Time!
- Look at Side AB and Side CD. What do you notice about their lengths?
- Look at Angle A and Angle C. Are they the same or different?
- Can you drag the corners to make all 4 sides equal?

👉 Drag any corner. The top and bottom sides are locked to always be parallel.
🕵️ Detective Work!
- Grab a calculator! Add Angle A + Angle D. What is the total?
- Now add Angle B + Angle C. What do you get?
- Change the shape. Do those totals ever change?

🧩 Puzzle Time!
You have two identical isosceles triangles. How can you combine them to form a 4-sided Rhombus?
Hint: Drag the blue triangle to test your idea!
🎉 You Built a Rhombus!
Now, drag its corners. Look closely at the sides and answer this:
Why must all 4 sides of a rhombus be exactly equal? Where did those sides come from?
