include points, lines, and angles, planes and solids.
geometrical figures
are imaginary invincible
geometrical figures
is the movement of a point and latter only indicates position
line
considered as a point
mark in a drawing
represents as a corner
mark in a drawing
the intersection of 2 edges of an object.
mark in a drawing
plane with four sides
quadrilateral
a 90 degree angle
right angle
an angle that has 2 equal sides
isosceles angle
an angle that has no equal sides
scalene angle
sum of all angles in a triangle is?
180 degrees
plane figure bounded by a uniformly curved line
circle
what are two or more circles that have a common center?
concentric circles
What are two or more circles that have an uncommon center?
eccentric circles
a geometric figure that has a factors of a circle but with no common center
ellipse
a geometrical solid with a circular base and with sides tapering to a point.
cone
the point on the sides of a cone
vertex
is a solid figure the base of which is either square, triangular, rectangular, or polygonal shape.
pyramid
is a solid figure with a base either square, rectangular, or polygonal in shape.
prism
is a five-sides square prism that are equal in size with its base
cube
has a circular base and its sides are either vertical or inclined.
cylinder
a solid bounded by a uniformly curved surface at any point which is equally distant from a common center within.
sphere
is a plane figure with five or more sides
regular polygon
5 sides polygon
pentagon
6 sides polygon
hexagon
8 sides polygon
octagon
10 sides polygon
decagon
lines that are drawn from left to right
horizontal lines
lines that are sketched from the top and downwards
vertical lines
are drawn with finger movement
short lines
are made with arm movement
long lines
can long lines be drawn in segments?
yes
are lines which make an angle of 90 degrees with each other
perpendicular lines
in drawing pencils, which pencils are the hard ones?
H PENCILS
in drawing pencils, which pencils are the soft ones?
B PENCILS
for h pencils, how do you determine the hardest and the less hard pencils?
smaller number - less hard
large number - hard
for b pencils, how do you determine the softest and the less soft pencils?
smaller number - less soft
large number - soft
pencil that can make different thicknesses of lines by warying the pressure of the pencil against of the paper surface
conical
a pencil that makes wide lines depending on the width of the points
chisel
an angle that has 4 equal sides
equilateral angle
