What is a real-life example of a complementary angle?

Hint: In this problem, we can see some real-life examples of complementary angles. We should know that, anywhere right triangles occur, we can see complementary acute angles of the triangle. Here we can see about the complementary angles and some of the real-life examples.

Complete step-by-step answer:
Here we are going to see about complementary angles and their real-life examples.
We should know that two angles are called complementary angles if their measures add to \[{{90}^{\circ }}\] .
We should know that, anywhere right triangles occur, we can see complementary acute angles of the triangle.
We can now see some of the real-life examples.
For example, if a rectangular piece of bread is cut into two pieces along the diagonal, we get two right triangles shapes from them, with a pair of complementary angles.
We can also take a wall clock, where when the minute hand is at 12 and the hour hand is at 3, which gives a complementary angle.
We can see a cross road, which is a great example of complementary angles, where we can see two pairs of right angled ways, which represents complementary angles.

Note: We should always remember that anywhere right triangles occur, we can see complementary acute angles of the triangle. We should also know that, two angles are called complementary angles if their measures add to \[{{90}^{\circ }}\], if the angles add up at \[{{180}^{\circ }}\], then it will be supplementary angle.
