FAQs on RS Aggarwal Class 9 Solutions Chapter-13 Geometrical Constructions
1. How to Construct a 90-degree Angle With Only a Ruler and Compass?
Construction of a 90-degree angle is there in geometrical construction Class 9 solutions. First, you need to draw a line segment and name it ab. Now take the compass and keep it at the center point, cut an arc on ab with a small radius. Name the point as m. Now with the same radius as above and m the center, cut a small arc on the previous arc drawn. Take the same radius and n as the center, cut another small arc at p on the last arc. Again, with a center at n and radius more than np, draw an arc. Then with the same radius draw the arc that will cut the previous arc at q. Now join aq. It is the 90-degree angle.
2. How to Construct an Angle of 75 degrees and 135 degrees?
The constructions are there in RS Aggarwal solutions Class 9 Maths ch 13. Firstly draw a line xy. Then choose any point o on the line xy. Draw a semicircle taking o as the center that cuts the line xy at p and q. Now, construct a 90 degree at angle YOR. Further, construct the bisector of this angle 90 degrees. Mark the point at s where the bisector cuts the semicircle. Intersecting at point a, draw two arcs with s and t as centers. Angle AOY is equal to 75 degrees. Draw any line xy and take a point 'a' on it. Draw a semicircle taking 'a' as the center that cuts the line xy at p and q. Construct angle YAC equal to 90 degrees. Next, draw the bisector of angle XAC and name it as ab. Angle YAB is 135 degrees. All are in RS Aggarwal Class 9 Chapter 13 geometrical construction.
3. Write the steps to construct an angle of 60 degrees.
Construction of an angle of 60 degrees is given in RS Aggarwal Class 9 Chapter 13 Geometrical Constructions Solutions. First, you need to draw a line segment and name it, say, AB. Then take the compass at the center point and draw an arc with a small radius. Let’s say, we name this point as m. Then, taking m as the center point and taking the radius same as above, we cut another arc on the previous arc. We name this n. Join m and n and extend the line to make it more visible. Here we have a 60-degree angle.
4. Why are Class 9 RS Aggarwal solutions important?
R S Aggarwal solutions are important to let the students check if they have understood and grasped all the concepts correctly or not. Consulting the solutions after solving the sums will help the students gain clarity over whether they have solved all the sums correctly. If they get all the correct answers after checking the solutions, that means they have understood the chapter. This will, in turn, help the students in being more confident. If they don’t get the correct answers, students have to understand that they still don't have a hold on all the ideas, thus they need to solve more sums.
5. Where do I get all the solutions of R S Aggarwal and other resources for studying?
All the solutions of R S Aggarwal and other resources for studying are available in Vedantu. In Vedantu, you will get solution sets, revision notes, practice papers, previous year papers, etc. which are very helpful for students of Class 9. These resources are made by subject experts. All of these are available for free. Students can visit the Vedantu app or website and just download them in pdf format. These resources will surely help students a lot in preparing for their exams.
