CONSTRUCTION OF A
RIGHT TRIANGLE
IF THE ONE ANGLE OF A
TRIANGLE IS 90,IT IS
CALLED RIGHT TRIANGLE
Construction of a right
triangle when its hypotenuse
and one side are given
[RHS Triangle Construction]
Given: The hypotenuse DF
of a right triangle DEF is
4.2cm
E=90 and EF=3.8cm
To Construct: A right
triangle,
given the lengths of its
hypotenuse and one of the
sides
Draw a line segment EF of
length 3.8cm
.
With center F and radius 4.2cm,
draw an arc of the circle , to intersect
ray EX at D
Join DF
Thus, DEF is the required
triangle
