Wassily Kandinsky• Wassily Kandinsky was born in Moscow in 1866. He grew up in a

bourgois, cultured family and learned to play the piano and thecello. In 1886 he began to study law and economics at theMoscow University. After passing his exams he started a teachingcareer at the Moscow Faculty of Law. He had many interests and apparently a great gift to teach himself different skills.

• In 1895 Kandinsky saw an exhibition of French impressionists in Moscow with paintings of Monet and others. He was, at first, confused and would later describe how upset he was about Monet's painting The haystack. He thought that the painter had no right to paint things in a way that made it difficult to recognize the subject.

• In 1896, at the age of thirty, he decided to start a new career as an artist and went to Munich in Southern Germany. He enrolled at the Academy of Fine Arts for four years until 1900.

• Kandinsky became the theorist of abstract painting. In 1910 he created his first abstract work - a watercolor. In 1912 he published a book on the theory of abstraction.

• In 1922 he came back to Germany to teach and work at the Bauhaus in Dessau until 1933.

• When the German Nazis came to power in 1933, all modern art was considered as entartet (degenerated art) and the Bauhaus was closed in 1933. Kandinsky's works were removed from German museums and confiscated.

• The artist's next destination was Neuiily near Paris where he remained until his death in 1944.

PointA point is a location. It has no size. It is named

with a capital letter.

LineA line extends forever in both

directions.

SegmentA line segment

has two endpoints. The

segment does not extend beyond

those endpoints.

• •

RayA ray has one endpoint and

extends forever in the opposite

direction.

•

PlaneA flat surface that

extends in all directions. It has no

thickness

IntersectIf lines in a plane cross at a point, they intersect.

PerpendicularIf lines intersect at right angles, they are perpendicular.

ParallelIf lines in the same

plane do not intersect no matter how far they are

extended, they are parallel.

Skew LinesLie in different

planes they do not intersect and are not

parallel.

An angle is formed by two rays with the same endpoint.

The rays are the sides of the angle.

The common endpoint is

the vertex.

Wassily Kandinsky – “Composition IX”, 1939

Angles are measured in units called degrees.

A protractor is a tool that measures angles

Two angles are said to be complementary if they total 90°.

Two angles are said to be supplementary if they total 180°.

 Wassily Kandinsky: "Schwarzer Fleck", 1921

Adjacent angles share a vertex and a side but have no interior points in common.

Vertical angles are formed by two intersecting lines and are opposite each other. Vertical angles have equal measure.

Angles with equal measure are called congruent angles.

• Congruent Polygons have the same size and shape.

• A figure that can be folded into congruent halves has line symmetry.

• A reflection is the mirror image of a figure that has been “flipped” over a line. An image and its reflection are always congruent..

means “is congruent to”
