basics of geometry with practical images
1.
2. - the branch of mathematics that is concerned with the
properties and relationships of:
- points, lines, angles, curves, surfaces, and solids.
- The visual study of shapes, sizes, patterns, and positions.- The visual study of shapes, sizes, patterns, and positions.
11. Made up of two rays with the same start point.
The start point is called the vertex.
The two rays are called the sides of the angle. The two rays are called the sides of the angle.
23. Plane Figure:
A two-dimensional
shape (2D).
A shape on a plane.
IncludesIncludes
points, lines, polygo
ns, circles, triangles
, hexagon, pentago
ns, etc.
A plane figure is
any set of points on
a plane.
24. Quadrilateral- a plane figure having four
sides and four angles.
Parallelograms - a quadrilateral having both
pairs of opposite sides parallel to each other.pairs of opposite sides parallel to each other.
25. Equilateral Triangle
Three equal sides
Three equal angles,
always 60°
Isosceles Triangle
Two equal sides
Acute Triangle
All angles are
less than 90°
Right Triangle
Has a right angleTwo equal sides
Two equal angles
Scalene Triangle
No equal sides
No equal angles
Has a right angle
(90°)
Obtuse Triangle
Has an angle
more than 90°

Faces: Side of the space figure
Edges: Where two faces meet
Vertex or Vertices: the corners of the space figures

32. Repeating a shape over and over
and over and over and over and
over again, leaving no gaps
Tesselation
over again, leaving no gaps
between each shape to form a
BIGGER shape.
Another word for “tesselation” is
TILING!

Symmetry is having two sides of a whole
look like they reflect each other.
