Question

In a right angled triangle where angle A= 90°
and AB=AC. What are the values of angle B.

Answer 1

Answer:

45

Step-by-step explanation:

Sum of angles of triangle is 180 so

90+angle c+angle b=180

C+b=180-90=90 .....(1)

Now since ab=ac so its a isosceles triangle now we know that if ab=ac

Then

angle opposite to side ab=angle opposite to side ac

C=b put it in (1)

C+c=90

2c=90

C=45=b

Answer 2

in a right angle triangle one angle measure will be 90 in degrees definitely

so that is an angle which is named as A

so A=90°

so AB=AC then the two angles will be same as their distance from a is same

so triangle measure of all sides should be 180°180_90 =90

then two sides are remaining 90/2=45

so value of B=45°
