Well, honey, that's no ordinary triangle, that's an isosceles triangle. Two sides are the same length, so it's like those twins you can't tell apart. Just make sure to measure those angles too, we don't want any surprises popping up like a bad reality show.

The triangle with sides measuring 4cm, 5cm, and 4cm is classified as an isosceles triangle. An isosceles triangle has two sides that are equal in length. In this case, the two sides measuring 4cm each make it an isosceles triangle. Additionally, the angles opposite the equal sides are also equal in an isosceles triangle.
A scalene triangle.
A scalene triangle is a triangle that does not have a right angle in it (i.e. not a right angled triangle) and does not have two (or three) sides with the same length (i.e. not an isosceles triangle or an equilateral triangle). An example is a triangle with sides of length 4cm, 5cm and 6cm.
5cm
Because the sum of the squares of the smaller sides equals the square of the largest side: 32+42 = 25 and 52 = 25
It will be a right angle triangle with a base of 3cm, a height of 4cm and a hypotenuse of 5cm
