Question

13. Show that the sides 5 cm, 12 cm and 13 cm
make a right angled triangle. Find the
length of the altitude on the longest side.​

Answer 1

Answer:

by Pythagoras theorem

(13)^2=(12)^+(5)^2

169=144+25

144=144

LHS =RHS

hence proved that it is right angle triangle

area of right traingle is 1/2base X height

1/2X60

=30

by using formula 2(area of ∆)/longest side

2X30/13

60/13

=4.61

Answer 2

Answer:

13*2 = 12*2 + 5*2

169 = 144+25

169-25 = 144

144 = 144

LHS = RHS

Area of right triangle = 1/2B X H

= 1/2 x 60

= 30

2 (area of triangle / longest side )

Step-by-step explanation:

2 ( 30 / 13 )

60 / 13

4.61
