Answer 6

Origami is the Japanese art of folding paper. This ancient art relies on properties of Geometry to produce fascinating and beautiful shapes. For example, you can make a swan from a square piece of paper. The first figure in this illustration shows some of the creases for an origami swan that has been unfolded. ABCD is a square and DE bisects angle ADB and DF bisects angle BDC. Use these facts to classify triangle ABD by its side lengths and by its angle measures.

Answer 7

<EBD = 45º; <BDE = 22.5º; <DEB = 112.5º, it's option A

Answer 8
