consider the above figure.
given,
- LMN = 90°
SO, ∆ LMN is a right angle triangle.
here,
- LM = 8 cm
- MN = 6 cm
by Pythagoras theorem,
now we get,
- LM = 8 cm
- MN = 6 cm
- LN = 10 cm
QUESTION: FIND YXN
we know,
in any triangle if the midpoint of any two sides are joined, the produced line segment is parallel to the third side.
here, midpoints of the two sides MN and LN are X and Y respectively. they are joined.
so we can state that,
XY।। LM
but,
LMN = 90°
so,
YXN = LMN = 90°
QUESTION: FIND YN
Here,
Y is the midpoint of LN.
so, YN = 1/2 of LN
that is,
therefore,
YXN = 90°
YN = 5 cm
