This might be a right triangle.
Pythagoras' theorem give us the length of the hypotenuse as sqrt(1^{2} + 2^{2}) = √5 cm and hence the triangle has perimeter 3 + √5 which is approximately 5.236 cm. It might be an isosceles triangle.
This is two right triangles, each with hypotenuse of length sqrt(1^{2} + 1^{2}) = √2 cm and hence the triangle has perimeter 2 + 2√2 which is approximately 4.828 cm. It might be neither a right triangle nor an isosceles triangle. The perimeter depends on the exact shape of the triangle. Penny
The perimeter is still not determined. The base and height determine the area, but ... See the three pictures below.
