Question

find the area of a right angled isoceles traingle whose hypotenuse is d cm. other side is a cm ​

Answer 1

Answer:

Using the length of 2 sides and an angle between them A = ½ × b × c × sin(α)

Using two angles and length between them A = [c2×sin(β)×sin(α)/ 2×sin(2π−α−β)]

Area formula for an isosceles right triangle

A = ½ × a2

Answer 2
