Taking O as center and any radius, draw an arc cutting OA (as shown below) 2). It works by constructing an isosceles right triangle, which has interior angles of 45, 45 and 90 degrees. Step 3: Now refer the angle from 0 degree to 85 degree as from right side. (Right side generally). Ex 11.1, 4 Construct the following angles and verify by measuring them by a Protractor : 75° 75° = 60° + 15° 75° = 60° + (30°)/2 So, to we make 75° , we make 60° and then bisector of 30° Steps of construction Draw a ray OA. Taking centre as O draw an arc with any radius to cut the line L. Label the intersecting point of L and the arc as B. . To construct a 30-degree angle, you’ll need a compass, a straightedge, such as a ruler, and a pencil. Taking O as center and any radius, draw an arc cutting OA at B. See the proof below for more on this. construct a parallelogram HEAR, HE=5cm, EA=6cm, angle R=85°(degree). . Step 1 : Draw a line ‘l’ and mark a point ‘O’ on it. Step 2: Place the point of the compass at P and draw an arc that passes through Q. Now find the midpoint of it. construct a parallelogram HEAR, HE=5cm, EA=6cm, angle R=85°(degree). Again use compass and opened to the same radius (as of step 2). This question is only an example . I m stuck at many problems which consist of 80°, 85° and 110°.

Start by drawing a horizontal line and marking the left end “A” and the right end “B” to serve as the vertex of the angle. Then inorder to trisect it join the 60 degree arc and the point where you kept the compass. Make sure to keep the compass open to the same angle. (as shown below) 2). Draw an angle bisector OD to the and 0 1 2. 1 decade ago. You may need to download version 2.0 now from the Chrome Web Store. With … With … Now, use the the following steps to construct angles of (1)40° 2() 160° (3) 120° 1.Taking O as centre and any radius draw an arc which intersect OA at E and OO at F. 2.Taking E and F as centres and radius more than 1/2 EF draw arcs which intersect each other at P. Now, back to our angle ∠ BOA. Using compass, bisect this arc, which will give 85 deg. We use one of those 45 degree angles to get the result we need. lt has been proven that a 20 degree angle … Step 1: Draw the reference line as AB. Every successive points make 10 deg. Also, the angles which can easily be constructed with the help of a compass are multiples of 15 like 15°, 30°, 75°, 90°,105 0, 120°, 135°, 150°, 180° etc..Even trisection method of drawing angles can not be used, as the trisection method concerns the construction of an angle equal to one-third of a given arbitrary angle and hence,we can't construct all angles using the trisection method.
