Question

Find the area of an isosceles right angled triangle whose hypotenuse is 10 and base 8 cm

Answer 1

Answer:

Step-by-step explanation:

This is Isosceles Right Angled Triangle with hypotenuse sqrt(10). If one of the equal sides is x then x^2 + x^2 = 10

Therefore 2.x^2 = 10, so

x^2 = 5.

Area of Isosceles Right Angled Triangle is (x^2)/2. (This is very easy to determine and prove, hence using directly.)

Since x^2 = 5, Area is 5/2 i. e. 2.5 square units
