120 Degree Angle How To Construct 120 Degree Angle By Compass Youtube "learn how to construct a 120degree angle using just a compass and a straightedge in this step by step tutorial. perfect for students studying advanced geome. This video explains how to construct 30, 45, 60, 90, and 120 degree angles with a compass.
How To Construct 120 Degree Angle Youtube This video shows how to construct a 120 degree angle with the help of ruler and compass only.this is one of the most basic and important constructions to kno. Construct an angle of 120° using ruler and compass steps of construction draw a ray oa. taking o as center and any radius, draw an arc cutting oa at b. 3. now, taking b as center and with the same radius as before, draw an arc intersecting the previously drawn arc at point c. 4. with c as center and the same radius, draw an arc cutting the arc. Without changing the compass width, place the compass at point @$\begin{align*}e\end{align*}@$ and draw another arc to cut the first arc drawn in step 2 at @$\begin{align*}f.\end{align*}@$ step 4: join @$\begin{align*}bf\end{align*}@$ and produce it to obtain ray @$\begin{align*}bc.\end{align*}@$ the angle @$\begin{align*}abc\end{align*}@$ so. Follow the following step to construct 120 degree angle. 1). use ruler and draw a line segment bc of any convenient length. (as shown below) 2). now use compass and open it to any convenient radius. and with b as center , draw an arc which cuts line segment bc at q . (as shown below) 3). again use compass and opened to the same radius (as of.

Therefore, ∠aod = 120° 30° = 150°. then, ∠aod = 150°. 9. construction of an angle of 45° by using compass. step i: draw a line ab and mark the point o on it. step ii: draw an arc using o as centre cutting ob−→− o b → at m. now, use m as the centre and om as radius, draw another arc cutting the previous arc at n. An angle can be constructed either by using a protractor and a ruler or a compass and a ruler. let us now look at the steps of constructing a 50° angle using a protractor. step 1 draw a line segment oa. step 2 place the center of the protractor at point o. step 3 starting from point a in the clockwise direction and mark a point at 50.
