Three parallelograms are hinged at each vertex to create an arm that can extend and collapse for an exploratory spaceship robot. What is m<1?

Given:

Three parallelograms are hinged at each vertex.

To find:

The measure of angle 1.

Solution:

From the given figure it is clear that angle on the vertex = 122°.

Now let angle 2 be the vertex angle in second parallelogram as shown in below figure.

             (Vertically opposite angles)

Two consecutive angles of a parallelogram are supplementary angles.

Therefore, the measure of angle 1 is 58°.
