Prove that angle a b c of a triangle is 180

Posted by Aman Kumar 8 years, 3 months ago

CBSE > Class 09 > Mathematics

2 answers

Golua Singham 8 years, 3 months ago

Make a triangle ABC with one angleABC as a ,second angleACB as b and third angleBAC as c ....................... Make a line parellel to BC passing from c...................... Now we get,angleMAB=angle a(alternate interior angle)and angleNAC=angle b(AIA)................................ Now angleMAB+angleNAC+angle c=180°(linear pair).i.e angle a +angle b+angle c=180°..........hence ,sum of the angles of a triangle is 180°.

In a parallelogram,show that the angle bisector of two adjacent angles intersect at right angles

Posted by Mohamed Arfath 8 years, 3 months ago

CBSE > Class 09 > Mathematics

1 answers

Golua Singham 8 years, 3 months ago

Let's take a parallelogram ABCD.whose diagonal intersect at a point O..............................................then angleCAD+angleADB=1/2angleBAD+1/2angleCDA(adjacent angles of the parallelogram)=1/2(angleBAD+angleCDA)=1/2(sum of both the corresponding sides)=1/2×180°=90°.......... Hence,angleCAD+angleADB =90°........................as we know that sum of the angles of the triangle is 180°.... In triangle AOD =angleCAD+angleADB+angleAOD=180°.....90°+angleAOD=180°........angleAOD=180°-90°=90°.......from this,angleAOD=90°,hence it proofs that it bisects at right angles

Right angled triangles can have with all sides different if the anlgles are 90,30,60 or 90,40,50 or 90,20,70 etc but if the angles are 90,45,45 then it would be an isosceles triangle.

Why we need to use 22/7 in math to get answers

Posted by Amit Singh 8 years, 3 months ago

CBSE > Class 09 > Mathematics

Avanish Mishra 8 years, 3 months ago

Pi is an irrational no. so we use its approximate value which is 22/7 or 3.14

0Thank You

Suraj Prasad 8 years, 3 months ago

22/7 is a value of pi ., it is used in solving questions based on circular things., it is a constant value which we must have to use to get answers., it is derived by dividing the cicumference of a circle by its diameter., suppose a circle has its diameter 14 and circumference 44 Now if you divide 44 by 14 you will get 22/7 You can check this derivation by putting different values ....but at last you will get a constant value of 22/7 GOOD QUESTION
