GEOMETRY ART
By: Courtney Fischer
GEOMETRY•The mathematics of the properties, measurement, and relationship of points, lines, angles, surfaces, and solids.•Geometry is about real things, real shapes, real spaces, real perspectives•Geometry can be divided into Plane Geometry & Solid Geometry.•Plane geometry: flat shapes such as lines, circles and triangles…shapes that can be drawn on a piece of paper•Solid geometry: three dimensional objects such as cubes, prisms and pyramids.
ARTElements of art that relate to Geometry

SHAPEGeometry: an enclosed figure.
• Triangle• Square• Rectangle• Rhombus• Kite• Trapezoid
Art: An enclosed space, the boundaries of which are defined by other elements of art.
•Geometric- those which correspond to named regular shapes, such as squares, rectangles, circles, cubes, spheres, cones, and other regular forms
•Organic- shapes or forms having irregular edges or surfaces or objects resembling things existing in nature.
PerspectivePerspective creates the feeling of depth through the use of lines that make the image appear to be three dimensional. The closer the image is, the more detailed it will appear, and the larger it will be.
•The invention of linear perspective is attributed to the Florentine architect Filippo Brunelleschi•He came up with the principles of perspective which were later on summarized as• 1: The horizon appears as a line• 2: Straight lines in space appear as straight lines in the image• 3: Sets of parallel lines meet at a vanishing point• 4: Lines parallel to the picture plane appear parallel and therefore
have no vanishing point•three rules of perspective to keep in mind when drawing. • elements in a drawing must have proper dimension and
size• elements in the drawing must relate to the viewers
distance• elements go along correctly with one another.
TYPES OF PERSPECTIVEOne point: easiest way to make objects three-dimensional
Two point: most commonly used perspectiveLike standing on the corner of a block and looking, so you
can see both sides of the block.
1. Draw in Horizon line and place one point on the line (vanishing point)
2. Draw object (house)3. From each edge on the object draw a line to the point on the
horizon(blue lines)4. Using the same angle of the original line, copy the line back along
blue lines. This makes the object 3-D5. Remove lines going to vanishing point6. Finish drawing
One Point
1. Draw in Horizon line and place one point on the line (vanishing point)
2. Draw object (house)3. From each edge on the object draw a line to the point on the
horizon(blue lines)4. Using the same angle of the original line, copy the line back along
blue lines. This makes the object 3-D5. Remove lines going to vanishing point6. Finish drawing
One Point
Two Point1. Draw in Horizon line and place two points on the line (vanishing
points)2. Draw a line Perpendicular to the horizon line in between the
vanishing points.3. From each edge on the object draw a line to each of the points on
the horizon(blue lines)4. Using the same angle of the original line, copy the line back along
blue lines. This makes the object 3-D5. Now add in windows by drawing a single line6. Draw lines from tops and bottoms of lines to vanishing point
corresponding with the side the window is on.7. Repeat step 48. Remove lines going to vanishing point9. Finish drawing
