If the hypotenuse of a right angle-triangle isosceles triangle is 2cm. What is the area of the triangle?
  • A.1/√2 cm2
  • B.
    1 cm2
  • C.
    √2 cm2
  • D.
    2√2 cm2
Correct Answer: Option B
Explanation

X2 + x2 = 22
2x2 = 4
x2 = 4/2
x2 = 2
x = +/-√2
Area of Δ = 1/2bh
= 1/2 x √2 x √2
= 2/2
= 1 cm2
