Class 10 Maths Important Board Question on Polynomial and Similar Triangles

Yeh image Class 10 Maths ka ek important question dikhata hai jo board exam ke liye bahut hi useful hai. Isme do main questions solve kiye gaye hain. Pehla question polynomial ke zeroes par based hai jisme sum of zeroes ka formula use karke k ki value find ki gayi hai. Yeh chapter Algebra ka important part hai aur board exam mein frequently poocha jata hai.

Dusra question Similar Triangles (∆ABC ~ ∆DEF) par based hai jisme perimeter ka concept use karke triangle DEF ka perimeter find kiya gaya hai. Yeh question bhi board exam ke liye bahut important mana jata hai kyunki Similarity of Triangles se har saal 2–4 marks ka question aata hai.

Is type ke questions practice karna students ke liye bahut zaroori hai kyunki yeh direct formula-based aur scoring questions hote hain. Agar aap Class 10 Board Exam ki tayari kar rahe hain to yeh question aapke liye must practice hai.

Can someone please tell me how you find the scale factor of a similar triangle with only angles, and not side lengths???

[purellis]

Is there anyone on who’s seeing this who’s good at math? Specifically, similar triangles?

Please, I need this done and turned in in twenty minutes but I’m stumped

Does anyone want to be super duper freaking amazing and help me with this calculus question

I will cry many tears of joy and give you my soul

Similar Triangles

Similar triangles have the same shape but are different sizes. Imagine you take a small triangle and place it on a copy machine and enlarge the triangle. The enlarged triangle would have all the same angle measures it would just be enlarged. This short video explains similar triangles and how to find missing sides.

Similar triangles are those in which the sides are all proportional to one another and all the angles are equal. So in the case of the two triangles above, we know that if they are similar then: 1.2.3.4.

2.  SSS (Side-Side-Side): The angles have had their fun. With SSS, we focus on the sides. Here we aim to prove that the three sets of corresponding angles are proportional to one another. Basically we prove #4 (see above). Again, remember that there is a relationship between the sides and the angles and so this is enough. Proving #4 ensures that #1-3 hold true as well. 3. SAS (Side-Angle-Side): Here we focus on proving that two sets of corresponding sides are proportional and then we prove that the angle between those two sides is congruent. In other words, we would prove that (a/d)=(c/f) and that angle C equals angle F. The rationale behind this approach can be seen through the law of cosines, which takes the lengths of two of the sides and the measure of the angle between them to calculate the length of the third side. 

Hope this helps!
