How do you draw a 120-degree angle? To construct a 120 ∘ angle, we follow the following steps for construction: Step 1: Draw a ray B A. Step 2: With B as the centre and any convenient radius, draw …

Dec 16, 2024 · Construct an angle of 120° using compass Last updated at December 16, 2024 by Teachoo

120° is greater than 90° and less than 180°. Therefore, a 120-degree angle is an obtuse angle. To illustrate what a 120-degree angle (120° obtuse angle) looks like, we drew the image below.

Constructing Polygons: Constructing regular polygons like hexagons or octagons requires constructing specific interior angles (e.g., 120° for a hexagon). Constructing Tangents: To draw a tangent to a …

The angle formed by the initial ray and the lines connecting the three points is a 120-degree angle. This construction works based on the properties of equilateral triangles.
