How to construct an angle of 75° with the help of a set square​

Answer 1

Answer:

Step 1: To construct an angle of 75°, use both the set squares in combination as (45° + 30°) = 75°.

Step 2: As there are two angles of 45° in a 45-degree set square, it can be placed in two different ways, and a ray OB can be drawn starting from the vertex measuring 45°.

Step 3: Now, place the 30-degree set square adjacent to the 45-degree set square.

Step 4: Draw a ray OA along the other edge of the 30-degree set square that is not touching the 45-degree set square, starting from point O. The angle so obtained is of measure 75°.
