Question

By joining two right angles. . angle formed

Answer 1

Answer:

The angle formed by joining two right angles is a straight angle( as it forms a straight line).

A right angle is of 90° and two such right angles when joined together, give rise to an angle of 180°, which is also called a straight angle.

A straight angle completely reverses the direction in the opposite way.

Answer 2

Answer:

The angel formed is straight angle.

Explanation:

Let us consider triangle named ABC with angle of 90 degree and consider another triangle named PQR with the angle of 90 degree.

Triangle with 90 degree is known as right angle triangle and with 180 degree is known as straight angle triangle.

By adding these two triangles, we get,

$90^0 + 90^0 = 180^0$

While adding these two right angles we will get a straight angle with the angle of 180 degree.
