Solution 1

Let ABC and DEF be two right triangles.

Solution 2

Solution 3

Solution 4

Let us consider that ABC is an equilateral triangle.
So, AB = BC = AC
Now, AB = AC  C = B         (angles opposite to equal sides of a triangle are equal)

We also have
AC = BC
B = A             (angles opposite to equal sides of a triangle are equal)

So, we have
A = B = C
Now, in ΔABC
A + B + C = 180o
A + A + A = 180o
3A = 180o
A = 60o
A = B = C = 60o
Hence, in an equilateral triangle all interior angles are of 60o.
