Constructing Angles of 60º, 120º, 30º and 90º

Constructing a 60 degree angle, constructing a 30 degree angle, constructing a 120 degree angle and constructing a 90 degree angle using a compass. An activity involving a compass and a ruler. In this section, we will consider the construction of some angles with special sizes. Constructing angles (video) Angles Khan AcademyClick to view2:41Mar 03, 2017 · Then we'll start getting into obtuse angles, 100, 110, 120, 130, 140, 150. And just to make sure that blue arc is measuring this angle right over here, not the outer one. And let me move the protractor out of the way so we can get a good look at it. And we got it wrong. So let's see what we-- oh, 155 degree angle, not 150 degree angle.

Construction of 45 Degree Angle with the help of Compass

1). Use ruler and draw a Line segment OB of any convenient length. (as shown below) 2). Now use compass and open it to any convenient radius. And with O as center , draw an arc which cuts line segment OB at X . (as shown below) 3). Again use compass and Construction of 90 Degree Angle with the help of Compass 1). Use ruler and draw a Line segment OB of any convenient length. (as shown below) 2). Now use compass and open it to any convenient radius. And with O as center , draw an arc which cuts line segment OB at X. (as shown below) 3). Again use compass and Construction of 90 Degree Angle with the help of Compass Follow the following step to construct 90 Degree Angle 1). Use ruler and draw a Line segment OB of any convenient length. (as shown below) 2). Now use compass and open it to any convenient radius. And with O as center , draw an arc which cuts line segment OB at X. (as shown below) 3). Again use compass and opened to the same radius (as of step 2).

Construction of Angles Constructing 30, 60, 90, 120

1. Constructing a 60 - Degree Angle:In an equilateral triangle, all the angles are equal and they are equal to 60° in size. Thus, in order to draw 60°, we need to construct an equilateral triangle. Step 1:Draw the arm PQ. Step 2:Then place the point of the compass at P and draw an arc such that it Construction of Angles Using Ruler and CompassConstruction of Angles Using Ruler and Compass - Concept - Examples with step by step explanation Apart from using ruler and compass, we can construct angles using ruler and protractor also. Sum of the angles in a triangle is 180 degree worksheet. Types of angles worksheet. Properties of parallelogram worksheet. Construction of Angles by using Compass, Construction of In construction of angles by using compass we will learn how to construct different angles with the help of ruler and compass. 1. Construction of an Angle of 60° by using Compass. Step of Construction:(i) Draw a ray OA. (ii) With O as centre and any suitable radius draw an arc above OA cutting it at a point B.

Construction of Angles for Different Degrees - Procedure

Construction of angles has been covered here. Learn how to construct 30 degrees, 60 degree, 90 degree, 45 degree and 15 degree angles using only a ruler and a compass. Click now to get stepwise lessons on angle construction. Ex 11.1, 2 - Construct angle 45 degree - Class 9 ConstructionsOct 05, 2018 · Ex 11.1, 2 Construct an angle of 45° at the initial point of a given ray and justify the construction . 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. Ex 11.1, 2 - Construct angle 45 degree - Class 9 ConstructionsOct 05, 2018 · Ex 11.1, 2 Construct an angle of 45° at the initial point of a given ray and justify the construction .

How to bisect an angle with compass and straightedge or

How to bisect an angle with compass and straightedge or ruler. To bisect an angle means that we divide the angle into two equal (congruent) parts without actually measuring the angle. This Euclidean construction works by creating two congruent triangles. See the proof below for more on this. How to construct 85 and 110 degree angles with compass Jun 03, 2012 · Angle trisection allows you to draw lines that divide the right angle into 3 sections, each being 30 degrees each. What you do now is that this angle, the 110 degrees one, goes PAST the right How to construct a 160 degree angle with a compass step 1 :draw a long straight line in your drawing paper. step 2 :set a definite arc in your compass and draw half circle as shown in figure. step 3 :using compass, cut two points C and D on semi circle. step 4 :from point D, cut an arc on E as shown in figure.
