The square ABCD, the side of which is 2 cm, is divided by the diagonal AB into two equal triangles.

The square ABCD, the side of which is 2 cm, is divided by the diagonal AB into two equal triangles. What is the area of each triangle.

In this task, we need to find the area of the triangles;

According to the construction condition, we are given a square ABCD with a side of 2 centimeters, which is diagonally divided into two equal triangles;

Recall that a square is a geometric figure that has four equal sides and right angles.

Since the diagonal divides the square into two equal triangles, the area of these triangles is equal to the area of the square divided by two;
St = Sq / 2. where St is the area of the triangle, Sq is the area of the square;

Sq = 22 = 4cm2;

St = 4/2 = 2cm2.
