Answer
Draw a perpendicular bisector, AD.
The perpendicular bisector of the base also passes through the midpoint of the base, effectively dividing it into two equal segments.
BD = DC = = 3 cm
According to Pythagoras theorem, in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
⇒ Hypotenuse2 = Base2 + Height2
In Δ ABD,
⇒ AB2 = AD2 + BD2
⇒ 52 = AD2 + 32
⇒ 25 = AD2 + 9
⇒ AD2 = 25 - 9
⇒ AD2 = 16
⇒ AD =
⇒ AD = 4 cm.
Using formula, area of triangle = x base x height
Here, base, BC = 6 cm and height, AD = 4 cm
⇒ Area of triangle = x 6 x 4 cm2
∴ Statement 1 is false, and statement 2 is true.
Hence, option 4 is the correct option.
