The area of an isosceles right-angled triangle ABC with a base of 50m squared. Height AH = 5√2 m.
The area of an isosceles right-angled triangle ABC with a base of 50m squared. Height AH = 5√2 m. What are the sides of the triangle?
We know the area of an isosceles triangle and it is 50 m ^ 2, it is also known that the Height drawn to the base of BC AH = 5√2 m.
In order to find the sides, we first apply the formula to calculate the area of a triangle and use it to find the base.
S = (BC * AH) / 2.
The area of a triangle is half the height times the base. Substitute the known values and find the base:
2 * 50 = BC * 5√2;
BC = 100 / 5√2;
BC = 10√2 m.
Consider a right-angled triangle formed by a height, half of the base equal to 5√2 cm and a side.
We are looking for the hypotenuse according to Comrade Pythagoras:
AC = √ ((BC / 2) ^ 2 + AH ^ 2) = √ (50 + 50) = √100 = 10 cm.
Answer: 10 cm, 10 cm and 10√2 cm.
