Use this worksheet to find the area of a kite.
1. What shape does the kite and the four triangles form?
2. What is the length of the sides of the combined figure in terms of d1 and d2?
3. Write a formula for the area of the combined figure in terms of d1 and d2.
4. Write a formula for the area of kite ABCD in terms of d1 and d2. (Hint: What is the relationship between the area of the original kite and the area of the new figure formed by rotating the triangles?)
