Complementary angles

• Complementary angles are two angles that add up to 90 degrees. As shown in the picture 25 + 65= 90 degrees.

Supplementary angles

• Supplementary angles are two angles that add up to 180 degrees. As shown in the picture 45 degrees plus 135 degrees, equals, 180 degrees.

Acute Angles

• Acute angles are the smallest type of angles. It ranges from 1 degree to 89 degrees. Acute angles are found in shapes such as rhombus, or a kite.

Right angles

• Right angles are strictly measured at 90 degrees. They are very common. They are found on countertops, squares, rectangles, and on many corners of everyday items.

Obtuse angles

• Obtuse angles are measured from 91 degrees to 179 degrees. They are found in shapes such as a pentagon.

Straight angle

• A straight angle is measured at exactly 180 degrees. They are found in train tracks, legs of a table, or light beams.

Reflex angles

• Reflex angles are the largest type of angles. They are measured from 181 degrees to 359 degrees. They are found in the outside angle of a shape.

First step

• Go to level 3 in the 6th stage.

• The level looks like this.

Where to shoot the birds

• The first bird you will shoot at about a 75 degree angle. If you shoot it just right, you will kill all the birds, except a little one, and it will be badly injured.

Last step

• This will be the last bird to shoot. If you shoot it at a perfect 90 degree angle, the last bird will be killed on contact.

3 stars

• To get 3 stars, you will follow the exact same steps that I did. If you shoot them at the same angles as I did, you will get 3 stars.
