Question

If one of the angle of a triangle is 130 the angle between the biestor of the other two other two angle can be

Answer 1

Answer:

The bisector of other 2 angles can be 155

Step-by-step explanation:

Let this be < Angle....

=> <A+<B+<C (Are the 3 angles in triangle.)

=>Sum of 3 angles is 180°

=> <A+<B+<C=180°

=>130+<B+<C=180° (Since 1 angle is given)

=> <B+<C=180-130

=> <B+<C= 50

=> After bisecting sum of the angle..

$\frac{(b + c)}{2} = 25$

=>Required Angle:180-25

=> 155°

=> Additional Information:

▪︎Congruency of the Triangles:

Things:

• The point of Intersection of the medians is called centroid of the triangle..

• An alititude of a triangle corresponding to any side,is the length of the perpendicular drawn from opposite vertex to that side..

•Median

• S.A.S. TEST

AB=DE

BC=EF AND ANGLE B= ANGLE E

SO TRIANGLE ABC= TRIANGLE DEF

•CONGRUENT TRIANGLES:

•TWO TRIANGLES ARE SAID TO BE CONGRUENT TO EACH OTHER IF THEY ARE EXACTLY CONCIDE..
