How to draw a 85 degree angle with ruler,compass and pencil.? 9) For 85 deg, mark 80 and 90 angle. Yes, it is. sides length given . 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°.
