angles
-
-
vertex
in 2D shapes, a point where two straight lines meet to make an angle;
in 3D objects, a point where three or more straight edges meet to make a corner
-
-
-
angle
two rays starting from the same point; the measure of turn between two lines, measured in degrees; the difference in direction between two lines
types of more angles
Supplementary angles
two angles that add together to make 180°
(Also see co-interior angles and supplementary adjacent angles.)
-
triangles
Isosceles
a triangle in which at least two sides are equal in length and at least two angles are equal in size
-
-
-
equilateral triangles
a triangle in which all three sides are the same length and all three angles will also be the same size (60°)
-
polygon
a two-dimensional shape where three or more straight line segments are joined together to form a closed figure; a plane figure with straight sides
-
-
more lines
-
-
parallel lines
lines that run in the same direction with the same gradient; lines in the same plane that are the same distance apart and do not ever intersect😁
ray
a straight line that extends infinitely from one point, called its end point
3D shapes.
polyhedra
(plural: polyhedrons or polyhedra) a 3D (three-dimensional) figure made by joining polygons at their edges
-
prisims
a solid where the base is a polygon and the other faces are formed by triangles with a common vertex (the apex)
A pyramid is classified according to the shape of its base.
-
pyrimids
a solid where the base is a polygon and the other faces are formed by triangles with a common vertex (the apex)
A pyramid is classified according to the shape of its base.
-
cylinders
a solid with two parallel, congruent circular faces connected by a curved surface

-
mass
The units of measurement we use for measuring mass are milligrams, grams,
kilograms and tonnes. The basic unit for measuring mass is the kilogram, which is

-
-
rhombus
a quadrilateral with both pairs of opposite sides parallel and all sides equal; a parallelogram with two adjacent sides equal in length
Example
-
circles
circle
a plane shape that is perfectly round
Each point on the circle circumference is the same distance from the centre.
-
time
period of existence that is measured in seconds, minutes, hours, days, weeks, months, years, and so on (or this process considered as a whole)
