Question

Some measures of angles are given below which angle cannot
be drawn using a set square? why?
15°, 75°, 115°, 135°​

Answer 1

Answer:

115⁰

Step-by-step explanation:

115⁰ because we can construct by set square

specific angles which are multiples of 15

Answer 2

Answer:

Any angle that is a combination of 15° can be drawn using a set square, and considering the angle options 15°, 75°, 115°, 135°​;   115° is not a multiple of  15°, so the angle 115° cannot be drawn using a set square.

Step-by-step explanation:

• Set Square is a triangular object that is used in engineering or technical drawing, used with the intention of drawing a straight edge in a right angled triangle.
• There are two types of set square; one having an angle of 45 degrees and the other having an angle of 30/60 degrees
• So a large number of angles can be drawn using a set square, and basically any angle that is a multiple of 15° can be drawn using a set square
• Considering the values given : 15°, 75°, 115°, 135°​; the 115° angle cannot be drawn using a set square.
