In an isosceles triangle, the base is 2 cm larger than the lateral side, but less than the sum of the sides by 3 cm. Find the sides of the triangle.
If it is an isosceles triangle, then the sides are equal.
Let x be the base of the triangle, then the sides = x – 2. Let’s make the equation:
x + 3 = x-2 + x-2
-x = -7
x = 7cm – the base of the triangle.
Then the sides: 7-2 = 5 cm
Answer: Side – 5cm, base – 7cm
