Transcript of The Geometric Book
The Geometric Book By: Aidan Gordon
Acute Angle
I took a picture of the ceiling because it makes an acute angle. An acute angle is an angle that measures less than 90 degrees.
Cone
I took a picture of this little Christmas tree because it looks like a cone. A cone is a 3-‐D shape. It has a circle on the bottom and a point on the top.
Cube
I took a picture of my rubiks cube because it is a cube. A cube has six faces and six vertices.
Intersecting Lines
I took a picture of this glass clock because it has intersecting lines. Intersecting lines are lines that cross each other.
Obtuse Angle
I took a picture of the ceiling because it’s an obtuse angle. An obtuse angle is an angle that measures more than 90 degrees.
Parallel Lines
I took a picture of these lines on the wood wall because they’re parallel. Parallel lines are lines that never intersect.
Perpendicular Lines
I took a picture of this door because it has perpendicular lines. Perpendicular lines are intersecting lines and most of the angles measure 90 degrees.
Triangle
I took a picture of this barn because it has a triangle on it. A triangle is an object with three sides.
Circle
I took a picture of the center ice at the Joe Louis Arena in Detroit because it’s a circle. A circle is a 2-‐D rounded figure, but from this angle it looks like an oval.
