Notations for Triangles:
Geometry
notations for triangles including the right triangle,
congruent sides of a triangle and congruent angles of a
triangle
Notation for
a right triangle:
The notation for
the right angle in a right triangle (or any other right
angle) is a little square in the corner.
Notation for
congruent sides of a triangle:
Little tick marks
are used to show that two sides are the same length
(congruent). You can use just one tick mark, two
or three or more -- just as long as you use the same
number on sides that are equal.
Notation for
congruent angles in a triangle:
This works a lot
like congruent sides (above)... You make the
little rounded sweep in the angle and then use tick
marks to show which angles are the same size (have the
same measure -- are congruent).
