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.

Learning Target: I can classify angles and work with pairs of angles.

Check your homework then review with your group members any questions you had wrong. If several

members had difficulty with the same question, be prepared to discuss that question when we

review. Next write down today’s Date and

Learning target in your notebook.

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.

Learning Target:I can classify triangles by side

and angle.I can find the angle measures

of triangles.

• Triangle – A closed figure made from three line segments.

• Sides with the same length are congruent sides.

• Equilateral Triangle – A triangle with three sides of the same length.

• Isosceles Triangle – A triangle that has two congruent sides.

• Scalene Triangle – A triangle that has no congruent sides.

• In order for three line segments to create a triangle, the sum of the two smaller segments must be greater than the larger segment.

• Acute Triangle – A triangle with three acute angles

• Right Triangle – A triangle with exactly one right angle

• Obtuse Triangle – A triangle with exactly one obtuse angle

• Parallelogram – a quadrilateral with opposite sides parallel and opposite sides the same length

• Rhombus – a parallelogram with all sides the same length, and opposite sides parallel

• Rectangle – a parallelogram with opposite sides the same length and all angles 90°

• 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”

• Rotation – the image of a figure that has been turned, as if it were on a wheel

• Clockwise – when the top of a figure is turned to the right

• Counterclockwise – when the top of a figure is turned to the left

• Rotational symmetry – when a figure can be rotated less than full circle, and the rotation exactly matches the original image

• Circle – Set of points in a plane that are all the same distance from a given point called the center,

• Radius – segment that connects the center of a circle to the circle.

• Diameter – segment that passes through the center of a circleand has both endpoints on the circle

• Central angle – angle with its vertex at the center of a circle.

• Chord – segment that has both

endpoints on the circle.

segments and perpendicular bisectors.

• Compass – A geometric tool used to construct a circle or part of a circle.

• Midpoint – point that divides a segment into two equal lengths.

• Segment bisector – a line, segment, or ray that goes through the midpoint of a segment.

Coordinate Plane

Coordinate plane – a grid formed by a horizontal number line called the x-axis and a vertical number line called the y-axis.

Ordered pair – give the location of a point written (x,y). The first number is the X-coordinate the second number is the Y-Coordinate.

Origin – Where the axes intersect. Indicated by the letter O.

The x and y axes divide the plane into four quadrants.
