Hii bro

[@geetugupta7244]

Same

[@bullshot3841]

You can prove it in a few steps by assuming b,q angles are in a same triangle

[@marinettedupaincheng9764]

Easier method
Draw a triangle (pbq) in which angle b and q are acute angle and angle p is right angle side
Given: sin b = sin q
Pq/bq = bp/bq
In which bq will cancel out
Pq=bp
Angle. B = Angle. Q (angle opposite to equal sides are equal)
Hence proved...

[@bhuvneshbhaskar2431]

Brother I was also thinking the same type of solution after seeing the(8.1) q6 solution
I had doubt that both are not same question but thx for clearing it

[@abhijeetkumar9193]

Thank you sir your video was helpful to me🙏🙏

[@walker5512]

How do we know that there are two triangles ? Can anyone explain?
Triangle ABC and triangle PQR

[@ZATeducation]

It was given in the question

[@Rekha_Mishra_]

​@@ZATeducationnahi bhai nahi diya hai... Exercise me same question hai but usko ek hi triangle me banaye

[@7angel4forever]

If we read the question properly well understand it not at first but after reading it few times so read the question 3 to
4 times if you didn't understand the question. In this question we know that we have to prove b= q so we will take two different triangle and and mark these two angle and about naming another sides we can name them anything we want for example triangle bpa or triangle qte but commonly we take abc and pqr or other names
Hope this will help you to understand 😊

[@Vanshkathuria000]

Sir can we take angle c =and r both 90degree then by sas rule both triangles are similar

[@fanblock_07]

You can't do it because the angle must be between the two sides then only we can apply Side Angle Side (in the rule too angle comes between the two sides)

[@sachindradas8229]

You can't do it because there are given that angle B and Angle Q is acute angle

[@EPIC_PLAYs]

Easiest best *explaination*

[@swativerma286]

Yeh koi define Kiya h ki triangle alg alg h ek hi angle me leke nhi kr skte kya like question no.6

[@Sneha____00048]

Q. If ∠A and ∠ B are right angles so that cosA= cosB, show that ∠A = ∠B.
SOLUTION,
B

| \
| \

A --------- Q
LET, the two acute angles ∠B and ∠Q are such that sinB = sinQ
=> AQ/BQ = AB/BQ
=> AQ = AB
=> ∠B = ∠Q [ Opposite angles of equal sides are equal ]

Sir, ye kya correct hai?
B

□____\
A Q
Let BAQ be a right triangle, right angled at A.
Now,
sin B = AQ/BQ
sin Q = AB/BQ
Given,
sin B = sin Q
=> AQ/BQ = AB/BQ
=> AQ = AB (Cancel BQ on both sides)
∴ ∠B = ∠Q (angles opposite to equal sides in a triangle are equal).
Hence Proved.

Sir hum last me is question se yeh bhi bol skte h na ki from theorem 6.4 if in two triangle, sides of one triangle are proportional to (i.e ., in the same ratio of ) the sides of the other triangle, then their corresponding angles are equal and hence the two triangle are similar by SSS (side-side-side) similarity criterion for two triangles therefore at last angle B = angle Q
