Question

an isolation triangle has equal triangle each 13 cm and base 24 cm in length, find height​

Answer 1

Step-by-step explanation:

the figure, AD is the altitude and Δ ABD is a right triangle. By Pythagoras theorem, AB2 = AD2 + BD2 ⇒ AD2 = AB2 – BD2 = 132 – 122 = 169 – 144 = 25 AD2 = 25 = 52 Height: AD = 5 cmRead more on Sarthaks.com - https://www.sarthaks.com/998361/an-isosceles-triangle-has-equal-sides-each-13-cm-and-a-base-24-cm-in-length-find-its-height

Answer 2

Step-by-step explanation:

In an isosceles triangle the altitude dives its base into two equal parts. Now in the figure, ∆ ABC is an isosceles triangle with AD as its height. (please refer the attachment.)

In the figure, AD is the altitude and Δ ABD is a right triangle. By Pythagoras theorem, AB2 = AD2 + BD2 ⇒ AD2 = AB2 – BD2 = 132 – 122 = 169 – 144 = 25 AD2 = 25 = 52

Height: AD = 5 cm
