FC: Angles and Transformations | Scrapbook by: Kory Sporney

1: Angles are two or less lines that Intersect, to create a ''Bent'' Line. | What are Angles?

2: An Acute Angle is an angle, but the degrees equal less than 90. To quickly identify an acute angle from a right angle, at the point of an acute angle, there should be a curve, when on a right angle, there should be a square. That leads us into right angles. | A right angle are two lines together that must be perfectly straight. The picture on the left is a right angle. However, it would normally have a square at the point of it.

3: To the left is an Obtuse angle. This angle measures out to more than 90 degrees. It is about the opposite of an acute angle. | The Complexity to your left is an Adjacent Angle. It has multiple angles in it, and they all share a common Vertex. This picture has 4 Right angles, 1 Acute, and 1 Obtuse.

4: The Next Angle is called a Vertical angle. It is an angle with two lines opposite intersecting, in the case on the right, It has two obtuse angles, and 2 acute angles within it. | The Next angle is a Complementary angle. It contains two separate angles that will equal up to 90 Degrees. They complement each other by creating a right angle. Of course, they both must be Acute angles.

5: Finally, A Supplementary Angle is two angles that both equal 180, A straight Line. However, it must be either an acute and an obtuse angle, or two right angles. | Moving into Transformations, Transformations are when you turn, flip, or slide a 2-D figure on a coordinate plane. The first Transformation is rotation. Rotation is Rotating a figure however many degrees, while one point stays the same. An example is when the planets rotate on an axis.

6: When you translate something, you are moving across your grid (The Coordinate Plane). It often is into another one of the Quadrants, or intersecting the Y or X Axis. | Dilation on a coordinate plane is when you increase the size of the figure. To the left, you see that through Dilation, the Circle grows bigger.

7: Reflection is making a mirror image of the figure over the X or Y Axis. | Rotation is moving a figure clockwise or counter-clockwise. You can rotate a figure by rotating it around a point, or you can rotate the entire figure. To the right you have a 3-D rotation, which is beyond the Coordinate plane.
